Headlines and analysts said for weeks the Republican tax bill would primarily benefit wealthy Americans and corporations. The Washington Post's Heather Long cited major cuts for both groups in a breakdown of the final bill.

GOP lawmakers are trying to take control of the narrative by targeting it to a very specific demographic: low-income single mothers.

Rep. Kristi L. Noem (R-S.D.) spoke at a news conference Thursday about a low-income mother in her district who was struggling to make ends meet.

“A while back I was grocery shopping on a weekend at about 11 o’clock at night and a mom came up to me and she had her handful of coupons and her grocery cart full of generic food and she said ‘Kristi, when is it going to get better?'" Noem said.

“By passing this bill and signing it into law, it just got better for that individual, for that family,” she said.

According to the National Center for Children in Poverty, 70 percent of all children with a single parent — 16.9 million — live in low-income families. Multiple Republican lawmakers have pledged the bill is mainly a big win for these families — a demographic President Trump has not done well with recently.

When GOP politicians gathered on the White House lawn Wednesday to celebrate the only major piece of legislation they passed this year, Sen. Tim Scott (R.-S.C.) also highlighted single mothers as one group he believed would benefit most.

“Let me just say to those Americans who are watching this process: this is not about Washington. It’s not about the Left. It’s not about the Right. It’s about single parent moms who are looking for a reason to be hopeful in 2018. This tax reform plan delivers for the average single mother a 70 percent tax cut,” Scott said.

Sen. Marco Rubio (R-Fla.), the son of a maid and a bartender, initially planned to vote against the bill because he did not think it benefited low income families enough.

The Post previously reported Rubio's hopes for the bill:

Under Rubio's plan, even if a family owed the government no money, the government would send that family a check if they qualify for the credit. That would allow them to still benefit just like wealthier Americans with big federal tax burdens to reduce. (During the tax debate, Rubio frequently noted that those who don't earn enough to have an income tax burden still pay payroll taxes, which automatically take money from Social Security and Medicare out of our paychecks. Rubio wanted these families, which don't pay income taxes, to also benefit from the tax credit by being compensated for their payroll taxes.)

In exchange for his vote on the final bill, Rubio only partly succeeded in revamping the Republican proposal to give some low-income Americans more money from the credit.

Republicans could use some more support from low-income families for their tax bill — only 24 percent of Americans support it, according to an NBC-Wall Street Journal poll.

If you remember, most working-class Americans voted against Trump in the 2016 election. His party’s members found themselves regularly dismissing the idea only the wealthy would benefit from the tax bill during the legislative process — and even after.

For the next eight years, the GOP tax bill gives the majority of Americans a tax cut, according to the nonpartisan Tax Policy Center. Only 5 percent will pay more next year.

Only time will tell if that will translate into midterm wins for a party barely clinging to its majority in the Senate. But it appears GOP lawmakers think that if they are to make any gains with demographic groups they have lost in the past, this narrative about single moms could help.
