As Victor Davis Hanson points out in his "The Second Coming of McGovern":
http://www.victorhanson.com/articles/hanson042408.html The Democrats are tottering at the edge of the abyss. They are about to nominate someone who cannot win, despite vastly out-spending his opponent, any of the key large states - CA, NJ, NY, OH, PENN, TX, etc. - that will determine the fall election. And yet not to nominate him will cause the sort of implosion they saw in 1968 or the sort of mess we saw in November 2000.
Yep. And their obsession with identity politics has led them right to this point. Here's hoping they walk right over the edge, and better yet blame their 2008 fiasco on voting machines again, so that they still will fail to learn :)
