I vote dem downballot because the republicans are worse and I would maybe consider voting dem for president if I lived in a swing state.
Also I only vote at all because I live in a vote by mail state (ballot gets mailed to me a couple weeks before election day, I fill it out in like 15 minutes and then drop it in a ballot box whenever I'm in town next), if I had to go stand in line at a polling place on a specific day I absolutely wouldn't.
