This sums up my feelings exactly (although I'd add that Trump is a fascist, as is anyone who supports him or pledges to support him). With that, here's what White House Spokesman Josh Earnest had to say a few minutes ago:
...the Trump campaign for months now has had a "dustbin of history"-like quality to it, from the "vacuous sloganeering" to the "outright lies" to even the "fake hair," the whole "carnival barker routine" that we've seen for some time now.
The question now is about the rest of the Republican Party, and whether or not they're going to be dragged into the dustbin of history with him? And right now, the current trajectory is not very good. Earlier this year, House Republicans elected to their leadership somebody who famously bragged to a reporter that he's David Duke without the baggage. Earlier this month, we saw that the executive director of the Senate Republican Campaign Committee was advising candidates about how they could ride the Trump wave. And just today - today - the newly elected Speaker of the House said that he would vote for Donald Trump for president if he's the party's nominee.
Now, I know that each of the Republican candidates has already taken an oath pledging to support Donald Trump for President of the United States if he wins the nomination. But the fact is, the first thing a president does when he or she takes the oath of office is to swear an oath to preserve, protect and defend the constitution of the United States. And the fact is that what Donald Trump said yesterday disqualifies him from serving as president. And for Republican candidates for president, to stand by their pledge to support Mr. Trump? That, in and of itself, is disqualifying.
