Here's a brief update on some 2010 primary races around the country:

NY Senate -- Bush Adviser May Run: Dan Senor, a former Defense Department adviser in the Bush 43 administration, "is expected to decide in the next month whether to run" against Sen. Kirsten Gillibrand (D-N.Y.) after state and national party leaders, including Rudy Giuliani and NRSC Chair John Cornyn, encouraged him to launch a bid, the New York Times reports. Republicans have been searching for a top tier recruit to challenge Gillibrand in the November special election -- especially following the GOP's success in the January special election in Massachusetts -- though there are a couple of Republicans who have already announced bids, so Senor would face a primary.

DE-At Large -- Wealthy Candidate Wanted: Delaware Republicans got a shot of good news earlier this week when a multimillionaire businesswoman named Michele Rollins announced she was considering running for Congress. The state GOP had struggled to find a candidate who could run on equal ground with former Lt. Gov. John Carney, giving Democrats perhaps their best opportunity to pick up a House seat in the 2010 midterms. Rollins' personal wealth makes her an attractive candidate for the national party, who would prefer to use its funds on races in Democrat-held districts. Rep. Mike Castle's (R-Del.) decision to run for Senate greatly increased the party's chances at picking up a Senate seat, but made his House seat one of the most vulnerable in the country.

AR Senate - Lincoln and Reconciliation: Sen. Blanche Lincoln (D-Ark.), in for a challenging primary race against Lt. Gov. Bill Halter, is again trying to make clear that she is against using reconciliation in an effort to get health care reform through Congress and to the president's desk. That's one issue the senator and her primary opponent disagree on, FOX News reported. "I get hit from the left because I am a moderate. I get hit from the right because I'm not far right and, you know, when you're in that crosshair it's a challenging time," Lincoln said, signaling a tough year ahead for her.

UT Senate -- Bennett Getting Clubbed: The Club for Growth has begun robocalling in Utah against Republican Sen. Bob Bennett, who is facing multiple primary challengers. The call asks voters to "vote for a change" in two weeks at the precinct caucuses, where delegates will be chosen and later tasked with selecting the party's Senate nominee.
