If you have ever sat in a focus group in a swing state, you are 100% certain that most soft partisans make up their minds on who to vote for based on things that are totally outside of an understanding of issues.

I was very surprised Barack Obama called Donald Trump "unfit to serve" during a press conference with the prime minister of Singapore. That is the sort of full-weight-of-the-presidency thing that I don't necessarily expect from Obama. So, why did he do it? I think he not only genuinely dislikes Trump but believes Trump would be dangerous as the commander-in-chief.

I think Donald Trump is simply incapable of sticking to a single message. Or of understanding that he doesn't know better than everyone else in every circumstance.

There are no more slow weeks. I realized this about 3 years ago. Downtime in politics isn't a thing.

Donald Trump is doing remarkably badly among non-white voters and there are lots of them in Arizona.

Donald Trump has been rewriting the rules since he got into politics.

I think the desire to reject elites, to retreat within more comfortable geographic and personal borders and to lash out at political correctness is not a phenomenon unique to Britain or the US.
