The one part of Obama’s stimulus that Romney loves

Mitt Romney's attack of Obama's stimulus is a central pillar of his campaign: In ads, statements, and speeches, he's attacked the law as a giveaway to the president's "friends, donors, campaign supporters, special interest groups." But buried inside Romney's economic plan is a promise to invest federal money in a new energy R&D program that was one of the stimulus's biggest success stories.

It’s not clear what Romney would actually cut to make his budget add up

Mitt Romney has promised vast reductions in federal spending while also balancing the budget, which would mean a whopping $9.6 trillion cut in non-defense cuts by 2022. He's largely avoided specifying what he'd actually cut to achieve such fiscal feats. And the cuts he has specified don't come close to getting him there.

What Paul Ryan’s budget actually cuts — and by how much

Both campaigns seem to agree that Mitt Romney's pick of Paul Ryan for the veep spot sets up a big, clear policy choice for the election. President Obama's vision for the federal budget is very different from Paul Ryan's. But what do these differences mean in concrete terms? Here's an analysis we did back in March, when Ryan released his 2013 budget, that tried to flesh the differences.

Ryan wants to give the wealthy even bigger tax cuts than Romney does

In picking Paul Ryan, Mitt Romney has doubled down on his own campaign promise to give big tax breaks to the wealthy, uniting himself with a candidate who goes even further to do so: While Romney would bring taxes for top incomes down to 28 percent, Ryan has proposed bringing the top rate down even lower, to 25 percent. Meanwhile, Ryan's plan would actually increase the effective tax rate on the very poorest Americans by getting rid of tax breaks that benefit low earners.
