2010: Gillibrand losing to McCarthy?

KANSAS: In the Kansas Senate Republican primary, "Discerning any major differences between Kansas GOP Reps. Jerry Moran and Todd Tiahrt requires a microscope, but as the Senate primary between them builds steam, wedges are beginning to be laid."

NEW YORK: Kirsten Gillibrand loses a Senate Democratic primary to Carolyn McCarthy, 34%-24% in a new Quinnipiac poll. If Gillibrand can hold on in the primary, she would beat Rep. Peter King in the race for Senate, the poll shows. (CORRECTION: We earlier incorrectly noted here and in the headline, Carolyn Maloney.)

Meanwhile, per the Washington Post's Cillizza, the RNC "is going up on television with ads in support of New York state Assemblyman Jim Tedisco in his special election bid in the state's 20th district, an early sign that newly elected chairman Michael Steele plans to wade into downballot races to reassert the party's competitiveness across the country and in the Northeast in particular. The ad, which was produced by Tedisco's campaign but funded -- to the tune of roughly $80,000 -- by the RNC, will be on Albany broadcast television, which reaches 80 percent of the district's voters, starting this evening."

Here's the ad.
