Another week, another primary. What can last night's elections tell us about this year's midterms?
If you're an incumbent, you're vulnerable. Like an audience at a pantomime show, people are yelling "Behind you!!!" It's wise to heed their warning.

In election after election since 2008, and especially notable in the last two weeks, GOP incumbents have been beaten by conservative candidates backed by the Tea Party. The Tea Party hasn't won all the races it's fought for, but it's a force to be reckoned with.

The question is, now what? Some people in the states that lost their incumbent member -- and even nationally -- may have their noses out of joint because their candidate lost. Well, them's the breaks. Fair's fair. If you now don't want to support the GOP nominee, that's fair too. But as our moms and dads taught us -- if you don't have anything nice to say, don't say anything at all. If you do support the GOP candidate, turn out is going to be key. General elections are a whole different ball of wax...so get rolling.
