I'm not going to wish for a recession but should one occur, the Dems need to adopt the narrative that they are good with the economy and the public needs to stop giving it back to the people that mess it up (GOP) every time it improves so they can do it all over again.
Unfortunately, people have a hard time remembering things like this. So, quite often it seems like while Republicans are in power, things do well (Bush inheriting Clinton's work, Trump inheriting Obama's, etc), and while Democrats are, things do poorly (Obama inheriting Bush's problems...) Throw in the regular partisan back-and-forth-ness, and you end up with a good portion of the electorate who legitimately believe that Republicans are better for the economy, as well as folks who know they're not, but are high enough income that they can ride the recession out and know the 'pubs will give them more kick-backs when things improve again.
I am honestly terrified for the next recession. We owe so much money, and instead of increasing taxes when we had the chance, we
cut them and raised spending on our pointlessly large military. If things go south in a hurry, people will realize how ridiculous it was to call the last recession the "Great Recession."
Luckily, 1.9% is not a recession yet. Here's hoping the Dems can get in soon enough to make the changes that need to be made. It sucks, because again, like with Obamacare, they'll only be in long enough to make the changes and then people will whine about having to pay more taxes and will give them the boot, but hopefully we can keep things from completely falling apart. As someone in the middle class, I would happily pay more taxes to keep things from falling apart.
