• Amanda Marcotte explains how the alleged killer of six people in California may have been driven by the ideology of a particularly ugly corner of the Internet:

This video and others that Rodger put on his YouTube channel were full of language that was immediately recognizable to many: He was speaking the lingo of the “pick-up artist” (PUA) community that feminists have been raising alarms about for many years now, arguing that it’s a breeding ground for misogynist resentment and may even be encouraging violence against women.

Feminist writers such as Marcotte are very familiar with these guys, because they’ve been enduring their rancid abuse on blogs and social media for years.

• Jonathan Cohn explains why President Obama’s coming regulations on power plant emissions are a big deal — and why there will be a huge political fight over them — with a comprehensive Q&A.

• In the journal Democracy, E.J. Dionne examines the conservative reformers who want to renew the GOP’s fortunes and finds that there may be less there than meets the eye.

• Dylan Scott suggests some questions about health care Republican candidates should answer, such as whether or not they want to repeal the Affordable Care Act.

• Over at the American Prospect, I made some graphs about those who have served and died in American wars.

• Like everyone thinking about running for president, New York Gov. Andrew Cuomo has a book coming out. And like those of many candidates before him, few people are likely to read it. But for some inexplicable reason, HarperCollins will pay Cuomo more than $700,000 for his book. Unless Cuomo enters a plural marriage with Kim and Kanye between now and 2016, I’m pretty sure the book is never going to generate that much in royalties.

• Sen. Richard Burr (R-N.C.) wrote an open letter to veterans groups castigating them for not joining Republicans in calling for VA Secretary Eric Shinseki’s resignation. The groups told Burr to shove it.

• Conservative writer James Pethokoukis blasts tea party Republicans for economic ideas that haven’t changed in decades: “If conservatives and Republicans desire a return to relevancy, then they can’t offer today’s voters reruns from the ’80s and ’90s in an attempt at solving yesterday’s problems.”

• Somebody just dropped $1.5 million trying to help Tom Cotton get elected to the Senate from Arkansas. Who? As Molly Redden of Mother Jones explains, we’ll probably never know, since the money was funneled through a “charitable organization” in Ohio. Can you smell the democracy?

• The New York Post got cheeky in reporting Kim and Kanye’s wedding (“Two jackasses got married in Italy Saturday. Sex-tape star Kim Kardashian, 33, wed egotist Kanye West, 36. . . .”). But Jim Romenesko responds, “That’s cute, NY Post, but you’ve devoted a lot of space to these ‘jackasses’ over the years.”

• And finally, a minor league baseball player hit a home run, which was caught by a fan in the stands who happened to be his dad. “He may have to watch every game from out there,” said the player.
