There was an article in Politico a few weeks back which suggested that Warren needed to build some credibility with moderates by attacking extremism within the Democratic Party. A Democratic version of “Nixon goes to China” sounds plausible. Could it happen?
It wouldn’t be easy. Warren has put a lot of effort into avoiding any daylight between herself and Bernie Sanders. Furthermore, she is a conviction politician; if you put “Nixon” and “conviction” in the same sentence, it has an entirely different meaning.
Nevertheless, it could be done. Warren could give a speech extolling the virtues of a better-regulated capitalism and calling out “democratic socialism.” Would she actually try it? Probably not until she has the nomination in her hands.
