Me voting or not voting for the Democrats here in California doesn't effect the election one bit
I still did it because they ditched the shitty old guy who said he wasn't going to run again, but I'm not pretending I've actually done anything in doing so
No. There are plenty of down ticket races even if your vote for the presidential candidate doesn't matter, it might very well make the difference between a good School Board candidate in your school district or a right wing book banning bible pushing nut job
It might be the difference between a normal city council or a far-right Nazi take over of your city council.
