From a commenter on Metafilter:
“I keep hearing that Democrats should either talk about economic issues or pitch their message to the emerging, more-diverse electorate — but I don’t understand why this has to be an either/or choice. Democrats who can’t figure out how to do both should get the hell out of big-league politics, in favor of people who can walk and chew gum at the same time. […]
“But please, please, please: Make the point that the Republican Party is the problem. The Republican Party has contempt for you if you’re non-white or LGBT or if you’re unemployed or need health care for a child with chronic illness or live downstream from a chemical plant. The key to changing America is not electing Republicans.
“But what are we doing? We’re fixating on Donald Trump and portraying him as an anomaly, not as the culmination of long-term trends in his party. We’re cheering on supposedly brave Republicans such as Bob Corker and Jeff Flake, ignoring the fact that the entire GOP, including, on most votes, Corker and Flake, has circled the wagons to protect Trump. We’re rehabilitating George W. Bush, which, as Ryan Cooper writes, is nuts: […]
“We’re falling into the trap Hillary Clinton fell into: We’re assuming that “real Americans” don’t trust any idea unless it’s ratified by a Republican, so we’re seeking Republican validation for our opposition to Trump. That just reinforces the notion that Democrats aren’t worthy of respect.
“Democrats: Be proud of who you are, speak up for yourselves, and talk about what Republicans have done over the past few decades and how their extremism hurts ordinary people. The problem is the Republican Party, stupid.”
