McHugh is the top Republican on the House Armed Services Committee.
Strikingly, McHugh wrote a recent op-ed in The Hill, in which he outlined his view of the ways in which Republicans can serve as the "loyal opposition" to Obama. He argued that the GOP must be more than "the party of no," and put forward a set of national security principles that he said the party should pursue.
The Washington Post's Chris Cillizza writes that McHugh's departure from Congress could "set off an extremely competitive special election for" New York's 23rd congressional district. "According to Swing State Project calculations, Obama carried the 23rd district 52 percent to 47 percent over Sen. John McCain (R-Ariz.) in 2008 and four years earlier George W. Bush won it by a similar 51 percent to 47 percent margin."
