What Flake is thinking about the tax bill

Sen. Jeff Flake, a key vote on the Senate tax bill, says he hates the budget “gimmicks" used to keep the bill from increasing the deficit by more than the $1.5 trillion limit. He also doesn't really buy the narrative that tanking the tax bill would throw the Republican party over a cliff.

Why it matters: While other Senate Republicans have similar concerns, Flake isn't running for reelection and has been openly critical of his own party. It's going to be much harder to twist his arm than it will be for other senators. He really wants to do tax reform, especially on the corporate side, but his vote seems truly up in the air.
