The war on the "far left" is an effort to move the Democratic Party to the right.

11. Don't those all poll well?

I don't know how you would define center, but the three things cited there have at least plurality support.

Basic left things like a $15 minimum wage, single-payer health care system, a mandate that the government achieve full-employment... none of that sort of thing is on the table.

It is always tricky to label things, but a failure to prevent people brought here as children from going to college doesn't seem leftist to me.

And whether Obama is pro-choice is not very germane. Pro-choice is the law of the land and the federal government isn't allowed to fund abortions, so he is not a huge player there.

And though there is some public support for rolling back the abortion maximum time-frame, America is surely not pro-life. There is nowhere near majority support for banning abortion categorically.
