Sarah Palin tweated an endorsment of come-from-behind physicist for Congress Ruth McClung:

Ruth McClung is the smart choice for Congress in southwestern Arizona. It doesn’t take a rocket scientist to know that our country is on the wrong track under the leadership of Obama, Pelosi, and Reid; but Ruth actually is a rocket scientist! Ruth’s commonsense fiscal approach to job creation and reining in reckless government spending is in sharp contrast to her opponent’s liberal record. In fact, Ruth is running against a four term incumbent who is so out of touch that he actually called for a boycott of his own constituents. It’s simple: The people of Arizona’s 7th Congressional District deserve better. Please visit Ruth’s website at http://www.ruth4az.com/ and follow her on Facebook and Twitter.

This is going to get McClung some press coverage, and no doubt some national money.
