In each of the following swing states, I looked at the ten latest polls as aggregated by the Huffington Post. This is the source of the data that I used. The decision on whether a state is a swing state is mine, not the Huffington Post’s. Here are the results:

Obama leads in 7 polls
Romney leads in 2 polls
Tie 1

Romney has been running ads in Minnesota. I did not count MN as a swing state. It is a Democratic state.
