I live in a state with partially open primaries that goes red 90% of the time. In order to maximize the effectiveness of my vote and thereby maximize my voice, I registered as an independent and generally request a Republican primary ballot.
I then have to sift through each list of candidates looking for someone who doesn't mention Trump and has a stated policy goal that isn't evil. There's usually one candidate who mentions their focus as being healthcare or education. This is a fairly laborious process and there are plenty of races where the least-worst option is still a horrible person. However, given the winner of the Republican primary has a 90% chance of winning the general AND voter turnout for the primary is generally under 10%, I know that this is effective.
Anyway, doing all this because it is the most logical course of action where I live and then seeing people cry about only agreeing with 87% of one candidate's policy goals always annoys the hell out of me.
