President Trump’s plan to make childcare more affordable for American families will barely help those of his supporters who need help the most, according to a new analysis.

On the campaign trail, Trump put forward a plan that he claimed would make the astronomical cost of childcare come back down to earth: allowing families to fully deduct what they spend up to a certain cap, while offering a “rebate” for lower-income families and tax-free savings accounts. Once in office, he promised he would be “fighting to make sure that all mothers, and all families, have access to affordable childcare.”
