Catherine Rampell: “Senate Republicans on Wednesday decided their party alone would control how math works. This is a pressing legislative question at present, because pretzeling budgetary outcomes into prettier shapes and sizes will determine whether Republicans can pass President Donald Trump’s promised tax cuts.
”“Those cuts are very expensive. Not only do they include extensions of the 2017 tax law provisions (set to expire this year), but they also lower corporate rates as well as carveouts for tips, auto loan payments and other goodies. In total, Trump’s preferred tax agenda could cost between $5 trillion and $11 trillion over the next decade.”
“This is inconvenient. Republicans like to pretend they’re fiscal conservatives (at least some of the time). They would prefer not to acknowledge the hefty price tag, and they also don’t want to fully offset it with unpopular spending cuts.”
“So, they’ve devised a cheat. Rather than admitting how much their tax agenda would cost, they are simply asserting that they get their first $4 trillion — free!”
