He has done this because it’s what he likes and wants to do. It has long been a conscious choice of this White House to pursue what David Plouffe, a key Obama adviser, called the “stray voltage theory.”

Major Garrett, then of National Journal and now of CBS, explained it in early 2014: “The theory goes like this: Controversy sparks attention, attention provokes conversation, and conversation embeds previously unknown or marginalized ideas in the public consciousness.

This happens, Plouffe theorizes, even when — and sometimes especially when — the White House appears defensive, besieged or off-guard.”

You can see how convenient such a theory is, since it works even when the White House appears to have blown it!

But this stray voltage has done nothing for any of his allies on Capitol Hill and has hardly advanced the liberal Democratic agenda.
