Your wife's a hate monger!!!! Haha, I kid.
While 700K doesn't seem like much, consider Obama got 951K in total for TN... which means 3/4 of the TN Democrats simply pulled the blue handle. And when you consider he was running for a Senate seat - the 2nd most important race on the TN ballot - and 3/4 of the Democrats voted for him tranlates to a lot of really uninformed voters. Simply voting the party - or in the Mark Clayton case... voting the party name, not the party line (since it's obvious that Clayton is not a real Democrat)
NOTE: I figure the Republicans that simply pull the red handle probably have a similar ratioPretty dissappointing to think that 3/4 of people (all people... D's and R's) who vote are probably uninformed.
CHIDORE... here's a Wash Post
article about Clayton The guy is a wacko that slipped through the cracks. I'm guessing the TN Democrats doubted that anyone could seriously challenge Corker and didn't pay as much attention as they did to other races.
