Wow. The GOP is really screwing up. Perhaps it is the Tea party influence and people are not liking the Tea party.
But in mid-term election with much of the world falling apart and people (unfairly IMHO) thinking the economy is in bad shape, the GOP should be doing great. But it seems pretty even. The GOP just has nothing to offer but the same old social conservative bullshit and obstructionism. That works for a sizeable minority of the country but it is not a big seller to the masses.
This is basically what Bernstein was saying. In a midterm, with a second-term president, with a mediocre economy, with the specific Senate seats in play, the GOP should probably be a lock to take control of the Senate. Their softness both in primaries and in general polls is really a warning sign for them. If they can't win in a year where Louisiana, North Carolina and Alaska are in play, they're going to be in a really bad place in 2016. They'll be defending Ohio, Florida, New Hampshire, Pennsylvania, Wisconsin, etc., with Warren* facing off against Santorum at the top of the ballot.
