Anecdotal evidence suggests that it’s quite possible. The “undecided” block has, in some previous elections, broken overwhelmingly toward one candidate, typically the one that is either underfunded or at a disadvantage in media perception (or both), as the “favorite” candidate fails to “seal the deal” prior to election day.
However, there’s no guarantee that that will happen in any given election; it’s just interesting to note that such a thing has happened before.
Look how Obama “finished up” against Hillary. If it weren’t for the Super Delegates and ACORN fraud, Hillary would have mopped the floor with him.
But don’t count out the corruption and fraud the Democrats are committing under our noses. And getting away with it Scott-free.
