I’ll vote for literally any Democrat in the general election, up to and including Satan himself or even Rahm Emanuel. But I just don’t see the benefit of “strategically” voting for a candidate I disagree with in the primary, due to some belief in “electability.” That is a purely speculative property. I don’t have the information necessary to decide that, and maybe no one does. Barack Obama sure seemed unelectable for a lot of common-sense reasons, but lo and behold, he actually got elected.
In any case I don’t trust the people who are trying to convince me of their personal theories of “electability.” Too much American political discourse takes place in those weird speculative meta-levels, where we’re supposed to choose the person we think other people will choose, or the person who will protect us from someone else. Every living American adult should be aware of the blackmail involved in the latter — and should be familiar with the disappointing results. Saving us from the worst looks an awful lot like the worst itself sometimes.
And again, we do not and cannot know for sure whether someone will actually win the election or protect us against the worst. What we do know for sure is each candidate’s policy proposals, and I think we should vote based on what we know instead of on our hunches about what other people (whose political preferences we don’t share or really understand) will think about the candidate at some future date.
The presidential candidate isn’t just a presidential candidate — they’re the leader of the party, who sets the agenda. Voting in the primary means voting on the direction of the party. If the Democratic Party is going to ask our opinion on that, we should give it to them sincerely, instead of psyching ourselves out through some ill-conceived 11-dimensional chess.
