Lots of rats came out to vote because there was a real race between Obama and Clinton.
Come November the same people that voted in 2004 and supported the GOP will be there again with a lot more urgency:
One interesting fact about Missouri is its status as a bellwether of national politics.
Missouri has a longer stretch of supporting the winning presidential candidate than any other state, having voted with the nation in every election since 1904 with the exception of Adlai Stevenson in 1956.
In 2004, George W. Bush won the state's 11 electoral votes by a margin of 7 percentage points with 53.3 percent of the vote.
Missouri has a very notable urban-rural split, as Democrat John Kerry only won three of the state's 115 counties: St. Louis County, Ste. Genevieve, and Jackson County (which contains most of Kansas City).-wiki
I just can't see it. The turnout for the rats is staggering. McCain just simply won't turn out the vote. I see a 45% to 30% win for the rat in November.
