And Obama won Lancaster County 54-46, because his demographic lives there.

Which is why they held the rally there, and not in Lebanon, just to north, which is where the Clinton demographic lives. Clinton won working class, Latino, and white and Latino Catholic voters of Lebanon County 56-44.

So what that tells us is, Obama only holds rallies in cities where his voter demographics guarantee the turn out they are looking for--politics 101. All politics is local.

The rally sizes are pretty meaningless at this point, unless people stop showing up to them, which doesn't seem likely today. In fact, the size of the rallies were only relevant in terms of giving him momentum going into Super Tuesday.
