Jeff Flake doesn't understand the Republican Party

“The former senator, who was a frequent critic of Trump, called on his former colleagues to put themselves through a “simple test.” And that involves asking, “What if President Barack Obama had engaged in precisely the same behavior?”

Jeff, they would reverse themselves. You should know, you were there. You watched your party reverse itself on executive oversight. The deficit. Golfing. Impeachment. On the issue of character in the executive. Free trade.

Quoting Paul Krugman from last year:

the real test came after 2016. A complete cynic might have expected economists who denounced budget deficits and easy money under a Democrat to suddenly reverse position under a Republican president.

And that total cynic would have been exactly right. After years of hysteria about the evils of debt, establishment Republican economists enthusiastically endorsed a budget-busting tax cut. After denouncing easy-money policies when unemployment was sky-high, some echoed Trump’s demands for low interest rates with unemployment under 4 percent — and the rest remained conspicuously silent.

Jeff, if you don’t know that your party acts in bad faith, on almost everything, no one should listen to you.
