What is it about Sen. Kirsten Gillibrand that makes so many people consider running against her? Today, two Republican candidates—one an economist, the other the father of a moderately famous person—announced that they will campaign against the appointed Senator.

According to the Daily News, former Bear Stearns chief economist and Reagan administration official David Malpass is trying to get his name on the ballot. Malpass—the president of the economic consulting firm Encima Global—says he will officially start his campaign next month, and in interview with CNBC cast himself as an opponent of government spending and the current health care bill, and evoked Republican Sen. Scott Brown's surprising Massachusetts victory.

Also in the race is former Congressman and Westchester Republican Joe DioGuardi—who is best known because his daughter is "American Idol" judge Kara DioGuardi. According to the Daily News, DioGuardi has faced "incessant questioning about Kara" since he declared his candidacy. New York Magazine notes that DioGuardi—the founder of a nonprofit that aims to decrease the national debt—sounded like a "die-hard tea partier" at his campaign kick-off at Grand Central Station this morning. "Are you ready to take your country back!?!" he reportedly shouted. "The new tyranny is Washington and Albany!"

On the busy Republican side of the ballot, Daily News publisher Mort Zuckerman considered running, but scrapped his plans. Amazing political ad-maker and former Port Authority commissioner Bruce Blakeman has already declared his candidacy. GOP leaders have been rallying behind former Bush administration official Dan Senor—who happens to be married to CNN's Campbell Brow. And there's even been talk that Mayor Bloomberg's girlfriend, Diana Taylor, might run.
