You can tell yourself that you’re voting left but the Overton Window still shifts right. Look at immigration. Look at the courts. Roe. It’s taking a hard right with the “left” candidate already in office.
If it’s going to go right either way, then focus your efforts on something else.
The change that I make might not “do anything”, but I am not going to just punch in Team Blue and then sit back and blame things on other people not voting the way you think they should have voted. That’s not doing anything at all.
