As it has to be, the more a candidate gets noticed, the more people start to look into their background. It’s happened to everyone in recent memory (Gennifer Flowers, Jeremiah Wright, etc. all came out of the woodwork), and now it’s happening to Herman Cain.

Poiltico went up Sunday with a blockbuster story of Cain’s time as president of the National Restaurant Association, the industry trade group that was Cain’s first foray into the Washington political scene.

Politico reports “at least two” women working at the NRA when Cain ran it “complained to colleagues and senior association officials about inappropriate behavior” by the man who is now the national frontrunner for the Republican presidential nomination.

So now the media and the blogosphere have something to talk about this week, and the cycle — the breathless revelation, a non-denial denial, an attempt to distract, backlash against the accusers, and accusations of hypocrisy from the candidate’s defenders directed to the appropriate side of the political fence — will go through its motions. You could play Bingo on the number of predictable memes you’ll hear coming from the Cain people and the other campaigns.

Also, these news stories don’t happen in a vacuum. Someone in another campaign has been doing their opposition research and leaked this story to Politico. Whether or not they’re doing it because they are having trouble with his jump in the polls or if they’re just tossing it out there as part of the overall campaign to bring him down on anything that sticks remains to be seen.
