Milton Wolf had his chance to make his case. He failed. There was no massive intrusion by the GOPe or dirty tricks like in Mississippi. I wasn't impressed by Wolf and saw him as nothing more than an opportunist. Roberts could be improved upon but he isn't that bad. Orman would be a disaster.
Roberts didn't need dirty tricks to win. He has the Stupid Party machine. But those wonderful moderates aren't going to vote for him in the general, and enough conservatives are going to stay-home or vote third-party.
GOP will not win the Senate. They will lose House seats.
