Sen. Kirsten Gillibrand can knock at least one name off the list of challengers to her reelection bid. Joe Carvin, a hedge-fund manager and Rye Town supervisor, announced Friday that he’s dropping out of the Senate race. “My No. 1 goal in entering the race was to ensure that the Republican Party had a nominee capable of defeating Ms. Gillibrand in November,” he said in a statement. “But in the last several days—after Ms. Gillibrand was ranked the most left-wing senator in America by National Journal and after she voted for higher gas prices by opposing the Keystone XL Pipeline—I believe any of the candidates in this race can beat her.” Carvin’s departure leaves more room for Rep. Bob Turner, who entered the race this week and is even using the same political advisers Carvin did.
