The Libya thing should start having its effect about the next two or three days.
If that does not change the outlook, nothing will.
For the demented Obamer nuts, it will not change a thing, but I am curious what it will do for the rest of the voters.
Take a look at the internals of this poll. They surprisingly broke it down by days. Each of the last three days, Romney has gone up vs. Obama.
Whether Libya or the debate, there is a definite suggestion of a drift upwards for Romney during this week.
