Why do you say the economy doesn’t motivate people to get out and vote? All you have to do is remind them that the Democrats plan to undo all this economic progress.
Because the Democrat candidate will deny they want to undo economic progress. There is no way to prove otherwise. It’s like a “He said/She said” thing. People just tune it out.
Plus, on a practical level, the tax cuts aren’t going away even if the Democrats win. That’s another reason running on them or the economy generally makes no sense. Pelosi can’t force a repeal of the tax cuts.
You don’t win races by running on something that has already happened. You win by talking about something that could happen but hasn’t happened yet, like impeachment or building the wall, and forcing your opponent to take a position on it. Plus the Dems have this “It started under Obama” theme. We know that’s nonsense but a lot of voters will just shrug their shoulders and say “I don’t really know”.
I’ve seen this movie before. Reagan presided over an economic boom in the eighties but there was a Democrat sweep in the 1986 mid-terms and the Republicans lost the Senate, right in the middle of a booming economy. Nobody who voted for the Democrats thought they were voting against the economy. Running on the economy, at least in mid-terms, is a loser.
