For the first time today in Pollster.com's trendline of multiple polls, Clinton's lead in Pennsylvania is under 5%. Of course, there is only one poll so far that includes some data after the blow up about Obama's "bitter" comments. And that one poll shows Clinton with a 20 point lead. But the trend line, at least for now, has dropped to below 5%.
We'll see if it stays that way after more new polls come in. Personally, I wouldn't bet on it.
But I guess we shall see.
