People would listen if they actually showed up. If leftists are so numerous then it shouldn’t be a problem to get many candidates elected. See mamdani. But in general they do not.

So either that many leftists don’t exist or their policies aren’t actually that popular OR theyre too lazy or ideological to go vote.

Either way, it ensures “establishment” candidates go on to the general election.

The only time your voice matters is in the voting booth. Far too many eschew that.
