Obama takes the latest Colorado poll by +4% over Romney, and he leads in four of the five current polls for the state.
Two polls in Connecticut both go to Obama. The Quinnipiac poll has Obama up by a modest +7%. A slightly older PPP poll has Obama up by +13%.
The latest Florida poll has Obama leading Romney by +4%. The current Florida polls go 4 to 2 for Romney, and Romney is given a 97% chance of winning the state right now.
Obama is up by +2% in the new Iowa poll. The candidates split the two current polls, but the poll that has Obama up is the much larger of the two:
In Michigan, Romney leads Obama by a weak +0.1%. The candidates split the four current polls, but the weight of the evidence has Obama up slightly with a 57% probability of winning an election held now.
The candidates split the two Missouri polls, with Romney up by +7% in one and Obama up by +1% in another. Obama has only led in this one poll out of the 6 current Missouri polls:
Nevada has Obama up by a slender +3% over Romney, slightly beating the +2% he had in the other current poll:
Little surprise that New Jersey has Obama up by a double-digit lead (+14%) over Romney.
In North Carolina, Romney has a +1% lead over Obama in one poll and the candidates are tied in another. The weight of evidence in the five current polls has Romney up by the slightest margin and a 56% probability of taking the state in an election held now:
Ohio is a tie at 45% each in the new poll. But Obama has led in three of the current six polls (with two ties), so the weight of evidence gives him an 87% probability of taking the state right now:
Another Pennsylvania poll gives Obama a +9% lead over Romney. Obama take all three of the current polls and would be expected to win an election now with a 99% probability.
Virginia is all tied up at 47% in the newest poll. Overall, Obama takes 4 of the six current polls, so he ends up with a 90% probability of winning an election held now.
Now, after 100,000 simulated elections, Obama wins 96,863 times and Romney wins 3,137 times (including the 449 ties). Obama receives (on average) 302 (-6) to Romney’s 236 (+6) electoral votes. In an election held now, we would expect Obama to win with a 96.9% (-2.3%) probability and Romney with a 3.1% (+2.3%) probability.
