I'm shocked, shocked, to find that Rudy Giuliani won't be running for the Senate in 2010.

So long, Rudy.

Former Mayor Rudy Giuliani is expected to announce Tuesday he is not running for U.S. Senate or anything else in 2010, effectively ending his storied - and often stormy - electoral career, The Daily News has learned.

The announcement, at which he'll also endorse Republican Rick Lazio for governor, marks the end of a year-long political dance by Giuliani, who mulled bids for governor and then Senate before backing away from both.

Giuliani has a long history of edging up towards big runs before backing down. In 2008, during his impressively unsuccessful Presidential bid, he pulled out of Iowa and effectively pulled out of New Hampshire. He has even backed out of a race for this very Senate seat before, dropping his 2000 Senate campaign in New York against Hillary Clinton.

Then again, it's probably worth taking this report from the New York Daily News with at least a grain of salt -- they did report just last month that Giuliani would be running for Senate in 2010 in preparation for a 2012 Presidential bid.
