As Jim Geraghty reported earlier today, a new poll from WMUR shows a dramatic restructuring of the Republican presidential race in New Hampshire. The poll shows Mitt Romney at 23 percent, down a full ten points from his commanding lead in July, with Rudy Giuliani just one point behind, at 22 percent, up four points from July. That’s right – in July, Romney led Giuliani by 15 points; now, it’s one. The poll also shows John McCain back in the game, with 17 percent – up from 12 percent in July – and Fred Thompson staying pretty much where he’s been at 12 percent.

A lot of observers have been expecting that Romney’s lead in Iowa and New Hampshire would begin to shrink a bit as the race accelerated after Labor Day. At least in New Hampshire, it appears to be happening.
