Democrats will almost certainly receive more votes than Republicans in the midterm elections. But gerrymandering and other factors have severely tilted the playing field, so they would need to win the popular vote by a wide margin to retake the House, and a huge margin to retake the Senate. I don’t know how it will turn out — or what will happen to the perceived legitimacy of the federal government if all three branches are controlled by people the voters rejected. Neither does anyone else.One thing we do know, however, is that Republicans have decisively lost the battle of ideas. All of their major policy moves, on health care, taxes and tariffs, are playing badly with voters.In fact, Republican policies are so unpopular that the party’s candidates are barely trying to sell them. Instead, they’re pretending to stand for things they actually don’t — like protecting health coverage for Americans with pre-existing conditions — or trying to distract voters with culture war and appeals to white racial identity. The G.O.P. has become the party of no ideas.
