I try to take a step back and look at the entire 2016 political situation as objectively as I can (I'm someone who could vote either Democrat or Republican depending on the candidates). Whether you believe in polls or not, Trump is seriously behind against Clinton. Also, Trump's inability to stick to the scripted speeches on the teleprompter have made a lot of tried-and-true conservatives anxious  these past couple of weeks. Republicans up for election in local elections and in Congress are faced with a real dilemma: either backing a candidate who eventually fails dramatically in November or failing to support that candidate and being labelled as unfaithful to the Republican fold for a long time (perhaps the rest of their political careers). In my humble opinions, a lot of these Republicans such as those mentioned here will vote for Trump but will minimize their comments in support of him so as to mitigate the risk of losing their entire careers (having the cake and eating it too).
