Donald Trump, Feb. 18, around 10:30 p.m., speaking with CNN's Anderson Cooper:

COOPER: If Obamacare's repealed and there's no mandate for everybody to have insurance, what's to — why would insurance company ... insure somebody who has a preexisting condition ...
TRUMP: Well, I like the mandate. Okay. So here's where I'm a little bit different. I don't want people dying on the streets, and I say this all the time. And I say this — look, I did five speeches, maybe six speeches today. We had a lot of rallies. We had of thousands and thousands of people. We get big crowds.
Every time I talk about this, I get standing ovations. The Republican people, they're wonderful people. They don't want people dying on the streets.

Emphasis added to CNN's transcript of the conversation.

Donald Trump, Feb. 19, around 3:30 p.m., on Twitter:

The possible middle ground? Trump likes the mandate but wants to repeal it anyway, potentially disappointing those voters who don't want people dying in the streets.

Either that, or Trump changes his stated opinion on things a lot, to the point that there's not much point in adjudicating this any further, so I should just stop typing and show you my goofy picture and bio.
