As always, the usual caveats. We’re still roughly four weeks out from election day and there are plenty of things that can happen between now and then.

That being said, this new poll shows Romney looking strong one week after his debate with the President.

In the 11 swing states, Mitt Romney earns 49% support to Obama’s 47%. One percent (1%) likes another candidate, and three percent (3%) are undecided.

This is the first time Romney has led the daily Swing State Survey since September 19. Until today, the president had led for 17 of the previous 19 days, and the candidates had been tied twice. This survey is based on findings from the previous seven days, with most of the responses now coming since Romney’s debate win last Wednesday night.

Ed Morrissey at HotAir gives a good breakdown of the poll.

The internals look pretty good for Romney, too, in this latest iteration. He has a 10-point lead among independents at 49/39, the latter a disastrous number for an incumbent just four weeks out from the election. Obama still leads among women, but only by five — and Romney leads among men by 11, for a +6 gender gap advantage. Obama has large leads among voters under 40 years of age (but not a majority among 30-39YOs at 49/37), while Romney wins solid majorities in all other age demos at 40 and above.

Moreover, Romney now leads by six among those “certain” of their vote, at 46/40. The soft numbers for Obama may be a real problem if he can’t dent Romney’s polling surge, as a preference cascade may wipe out the 7% that are leaning towards him now in these swing states. Romney does even better among independents in this measure, leading 43/31 among those “certain” of their choice. Romney has a 14-point lead among “certain” men (and a majority at 50/36), and only a three-point deficit among “certain” women, 41/44.

Those “certain” numbers will be key to watch over the next four weeks. If Romney can start solidifying support while Obama remains in the low 40s (or lower), the break of undecideds might be overwhelming.

All of this is encouraging, but it’s not enough.

A good debate tomorrow night by Paul Ryan will put the strength of the Republican ticket on display for a broad audience, and could help ensure that the trend towards Romney continues.
