The Worst Campaign Ever?

I’ve been a little bit surprised by the number of liberals who’ve been eager to proclaim John McCain’s 2008 campaign to be the most vile and dishonorable thing they’ve ever witnessed. It struck me as less vile and dishonorable than the other presidential campaigns (2004, 2000, 1996) that I remember.

Mind you, Matt thinks the McCain campaign was vile and dishonorable — just less so than most Republican presidential campaigns. This is in contrast to a number McCain critics who enthusiastically supported George W. Bush in 2000 after Karl Rove’s stridently negative South Carolina primary campaign.
