I'm not comfortable about directly awarding office to candidates that most of the electorate voted against.
Even if the runoff is between two candidates that didn't get a large percentage of the vote,
at least a decision is made as to the lesser of two evils. I often have to do that,
vote for a Democrat I don't particularly like to stop the Republican,
although I actually liked Harris.
In an election where, say, four or six people will be seated,
there's nothing wrong with voting a bullet for the one you want most.
