Writing for the LA Times, and echoed by msn.com, Matt Lewis advises the sad sack Democrats as follows.
People don't vote based on governance--they vote based on vibes. Trump's vibe is chaos, but it's charismatic chaos. His base doesn't care if he burns down the country as long as he looks cool doing it.
[Democrats] really have to stop being culturally insufferable.
If they want to win, they need to talk like normal human beings again. Right now your average Democrat sounds like an NPR panel discussion moderated by a yoga instructor with a Whole Foods tote bag.
Less conspicuous compassion and more old-fashioned patriotism would also help a lot.
