This is the most telling result from Super Tuesday.
Democrats turned out more than twice as many voters as Republicans did. Just look at the vote totals recieved by each of the major candidates:
Clinton and Obama each recieved more than twice as many votes as McCain did and nearly as many votes each as all Republican votes cast period. Simply put, there is great enthusiasm for the Democratic candidates and much less enthusiasm for the Republican candidates. If this trend continues through November, it should be a blowout election regardless of who the Democratic nominee is.
