Early voting

I may mention this again tomorrow in a predictions post, but I kinda want to put early voting into the discussion.

Alot of the states involved in Tuesday's primaries allowed various forms of early voting which basically boils down to two main groups: 1) Absentee voting where a decision is made several weeks or more before the election, and 2) The newer early voting where limited polling stations are open two weeks or so before the primary for people to cast votes.

The Clinton campaign put alot of early effort into getting their targeted voters to cast early, locking them in. So, as you see the polls closing up in states like California, keep in mind that there are vast numbers of these early voters that may not break along this late "Obama's closing" polling trend.

Of course, they could also represent the Clinton base who wouldn't be changing their mind anyway.

Just putting it out there.

Later: Josh Marshall makes a decent counterargument.
