OK, this is pretty funny, if you like weedy political arcana. Out in California they have open primaries where the top two finishers end up on the November ballot. In a number of House districts there are so many Democrats hoping to lead The Resistance this fall that a number of primaries are shaping up as two Republicans versus ten or so Democrats.
For those with a modest flair for math (i.e., not a lot of Blue consultants) this creates a real possibility that in swing districts the two Republicans will split around 50 percent of the vote and ten Dems will split the remainder. The two candidates with the most votes will be Republicans, which will make it hard for the Dems to win the seat in November. Ooops!
Once again, the left hand doesn't know what the far left hand is doing.
