Broadly speaking, Donald Trump is not popular with the ladies.

A Washington Post-ABC News poll published Sunday found that 69 percent of women have an unfavorable view of him, including 59 percent who see him in a "strongly unfavorable" light.

When Republican lawmakers — male or female — hesitate on whether to support Trump, they often cite his controversial comments about women as a reason why. (We'll note that while Trump struggles with women generally, Republican women don't seem to differ on him in any major way from Republican men. That same Washington Post-ABC News poll found that roughly 1 in 3 have an unfavorable view of Trump, regardless of gender.)

Given Trump's struggles to get American women to like him, we wanted to know more about the women who are speaking on his behalf this convention. Here's a rundown of some of the notable politicians, conservative leaders and even an astronaut who will be speaking in the next few days.

Sen. Joni Ernst (R-Iowa)

Her conservative cred: Ernst is part of the class of senators who won in the Republican wave of 2014. She won a hard-fought contest for an open seat and is the first Iraq War veteran and the first woman to represent Iowa in Congress. She got national media attention for her campaign ad, "Squeal," touting her experience castrating hogs. And she rides motorcycles.

What she's said about Trump: She was reportedly on his shortlist for vice president, but earlier this month, she essentially took her name out, telling Politico she wanted to stay in the Senate. She's said she'd help him get elected, but she hasn't really gone all out to support him or say nice things about him. "I would love to assist him out on the trail," she told Politico's Burgess Everett.

When she's speaking: Ernst already spoke Monday night — but because she came long after headliner Melania Trump, her address fell on a mostly empty convention center, which made for awkward television. Still, she used her military and national-security service — security was the theme for Monday — to praise Trump, who she said "will not hesitate to call radical Islamic terrorism by its name, and to destroy those that wish to harm our nation.”

Sen. Shelley Moore Capito (R-W.Va.)

Her conservative cred: Moore Capito is another conservative star who won her seat in 2014 and helped Republicans take back the Senate. She was the first woman from her state to be elected to the Senate and the first Republican from the state to win a full term since the 1940s (although she's been in Congress for some 14 years). She quickly became a member of Republican leadership, and her ties to the West Virginia Republican Party are deep, given her father was the state's governor.

What she's said about Trump: Some of her only public remarks on him have been critical of his "tone" toward women voters. "I'm just going to emphasize that what you say and how you say it is really important," she told CQ Roll Call's Bridget Bowman in May before a Capitol Hill meeting with Trump, where she was one of the few female lawmakers to talk to him. She also told Bowman "he's a strong leader."

When she's speaking: Moore Capito will be one of the last speakers Tuesday night, when the theme is "Make America Work Again."

Oklahoma Gov. Mary Fallin (R)

Her conservative cred: Yet another conservative female lawmaker, yet another reported vice presidential option for Trump. Fallin has been the governor of Oklahoma, one of the reddest states in the nation, since 2011 and is one of the most active anti-abortion advocates in a governor's mansion right now. She was the co-chair of the party's platform committee during the convention, a job that potentially put her at odds with Trump's sometimes softer stance on abortion than those many social conservatives like herself hold. (The committee ultimately adopted a strong anti-abortion position.)

What she's said about Trump: Unlike some of the women on this list, Fallin has been a vocal supporter of Trump. She endorsed him in May at the height of veep speculation, saying she supports him "100 percent." In a CNN interview shortly after the Dallas police shootings, she said she thought Trump was "trying to campaign as a racial healer."

When she's speaking: Thursday night, when the theme is "Make America One Again"

Rep. Marsha Blackburn (R-Tenn.)

Her conservative cred: Blackburn has been in Congress for more than a decade and is one of the House's leading anti-abortion advocates. She was also one of the most vocal critics of the Affordable Care Act and is a questioner of climate change.

What she's said about Trump: When Trump clinched the nomination in March, Blackburn said she'd consider being his vice president — even though a few days earlier, she had criticized him for not wholly denouncing an endorsement from former Ku Klux Klan leader David Duke. She now acts as a surrogate of sorts by talking about her support for Trump — she likes his "retirement security" plan — on TV.

When she's speaking: Like Fallin, Blackburn will speak Thursday night, when the theme is "Make America One Again."

Leslie Rutledge, Arkansas attorney general

Her conservative cred: Rutledge is relatively new to the political world, serving as Arkansas's top lawyer since 2015. She has since challenged some local anti-discrimination protection laws for LGBT people. Part of her appeal for Republicans is that she comes from the state that launched Bill and Hillary Clinton's political careers.

What she's said about Trump: Rutledge hasn't really been a figure on the national stage, but in the few media interviews she's done leading up to the convention, she's attempted to cast the Republican Party as "extraordinarily unified" while not saying much about Trump.

When she's speaking: Rutledge will be one of the first speakers Tuesday night, when the theme is "Make America Work Again."

Laura Ingraham, conservative radio host

Her conservative cred: Ingraham has had a popular talk-radio show in some form or another since 2001 and is a frequent guest on Fox News' "The O'Reilly Factor."

What she's said about Trump: Throughout the primary process, some conservative radio hosts and bloggers were among the loudest defenders of Trump, whose campaign ethos fit neatly with their anti-establishment views. Ingraham was a staunch Sen. Ted Cruz (R-Tex.) supporter, but as it became clearer Cruz was not going to win the nomination, she started defending Trump, too.

When she's speaking: Ingraham will be the first speaker Wednesday night, when the theme is "Make America First Again."

Pam Bondi, Florida attorney general

Her conservative cred: Bondi, a Florida native, has been the state's top law enforcement official since 2011. She's a social conservative opposed to same-sex marriage, a position that put her in an awkward interview with CNN's Anderson Cooper immediately after the mass murder at an LGBT nightclub in Orlando.

What she's said about Trump: She's been associated with him politically for years, an association that has sometimes gotten her in trouble. In 2013 Bondi came under scrutiny by campaign finance watchdogs for accepting $25,000 from one of Donald Trump's foundations then later deciding not to join a fraud lawsuit against Trump University. She's also appeared at rallies for him in Florida and officially endorsed him in March, after he had won the nomination.

"We need someone who is unafraid to lead and restore America to its greatness,” Bondi said.

When she's speaking: Bondi will be one of the first speakers Wednesday night, when the theme is "Make America First Again."

Eileen Collins, former NASA astronaut

Her conservative cred: Out of this world (literally). Collins was the first woman to fly a space-shuttle mission and the first woman to command one. She's a former military pilot and an inductee of the National Women's Hall of Fame.

What she's said about Trump: Not much. In fact, her decision to speak here surprised many of her fellow astronauts. “She’s a low-key, extremely pleasant, not strident, not aggressive personality,” John Logsdon, founder of the Space Policy Institute at George Washington University, told Speaking of Science's Sarah Scoles. “So frankly, it’s a bit surprising to me she’s willing to do this. But it must represent her thoughtful views.”

When she's speaking: Collins will be one of the first speakers Wednesday night, when the theme is "Make America First Again." That's also the 47th anniversary of the first mission to the moon.
