Well, I hope the Clinton campaign knows what they are doing. I'm assuming they did a lot of testing and polling and focus-grouping. I'm not really enthused about Kaine and I'm concerned playing it too safe/cautious will cost her the election. The Dems have a long history of losing when they are boring (Dukakis, Gore, Kerry) and frankly, being too cautious and safe is why Hillary got stomped by B. Obama in 2008.
Seems kind of odd to draw broad conclusions based off 2000 or the 2008 primary considering they were decided by a knife's edge. You must have a very strange definition of "stomped."
