* Mitt Romney’s forceful performance in the first presidential debate could not only benefit him but help Republican congressional candidates throughout the state. Rep. Peter King believes that Romney stopped a Democratic surge in swing districts in Long Island, Central, and Western New York. “Now it becomes mano a mano, and talk about the ‘47 percent’ have been nullified, at least until the next debate,” he said to an audience at Bryan Cave LLP in Midtown Manhattan on Thursday night. That could benefit Republican incumbents Rep. Nan Hayworth and Rep. Ann Marie Buerkle, as well as GOP congressional hopefuls, including Chris Collins and Randy Altschuler, who are all engaged in competitive races this fall. “Riding a presidential candidate’s coattails won’t help sweep in a House candidate, but it can help in a close race,” King said.
