The Republican candidate picking process picked a repugnant candidate for the Senate, which might mean that a potential switch in representation (as Senator Michael Bennet was considered vulnerable) won't happen. They picked Darryl Glenn, who among other things would put Ted Cruz on the Supreme Court if he had the chance. Reading about him, Mr. Glenn redefines political loose cannonness and jerkiness. (And I could say worse.)
This is good news for Democrats, obviously bad news for Republicans, and that's basically good for everybody, even if the Repubs don't realize it.
