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.

Forty-six percent (46%) of these Swing State voters are now “certain” they will vote for Romney and will not change their minds. Forty percent (40%) are certain they will vote for the president.
