The GOP, the Stupid Party, finally woke up to discover that they should do the same thing. In 2008 the Dems clobbered the Reps in early voting--40% of the votes are cast before election day. Now it appears so far that the Dems ground game is not as good as 2008, i.e., they are not getting out as many of their base to vote early. The GOP is doing much better than 2008, which shows they are learning their lesson and they appear to be much more motivated.
So heavy early voting is a good indicator of how the race may be going and it could be a good or bad sign depending upon the relative numbers. So far, the GOP is exceeding its 2008 numbers while the Dems are under performing. In 2008, John McCain received more votes than Obama on election day. But Obama won by 10 million votes, much of them cast prior to election day.
Makes sense...thanks.
