Romney is up by 5 in Florida and down by 1 in Ohio. And both of these are trending towards Romney.
Romney is up by 3 in Virginia and 4 in Colorado. and tied in Iowa.
Your are correct about Pennsylvania. Obama is up by 5, but that is also trending towards Romney.
Ohio looks like the lynch pin, although with Virginia, Colorado and Iowa romney is at about 261. So if Wisconsin went he could win without Florida.
