Peggy Noonan points to the Obama-Lincoln exchange a few days ago as critically telling. As he made clear, he thinks that moving to the political center is a losing proposition. He is also willing to settle for being a one-term president rather than change his political course. Politicians usually don't think like that. According to Noonan, Democrats are going to have to revolt against a potential one-termer who is willing to sacrifice them for his agenda.

You can find several versions of the Obama-Lincoln exchange on the web. See the Washington Post here.

The LA Times identifies Lincoln as one of the Democrats across the country who want to keep Obama out of their campaigns.
