Susan Collins and some other senators who had hinted they might oppose the Republican tax bill giveaway to the super rich are changing their tune. Apparently, President Trump assured them over lunch that he’s going to fix the bill.

Are they actually that clueless? Or do they merely think the rest of us are?

One of the few certainties in these uncertain times is that no one can rely on anything Trump says. But these senators believe him now? The only other option is that they know Trump’s pledges to “fix” the tax bill are insincere and they are conning their constituents and the rest of America.

Neither possibility is appetizing, but that’s where we are after Trump met with Republican senators to talk about the tax bill.

Participants told reporters that Trump was paying attention and seemed to understand the details. Think about that. It’s news when this president seems to grasp an even slightly complicated idea.
