Is Dick Lugar going to be the Bob Bennett of 2012?  Bennett was a popular Republican senator from Utah who was deemed too moderate for his Republican constituents, who replaced him with Tim Lee as the Republican nominee for Senate in 2010 (and who went on to win in November).  Now, Lugar seems to be slipping in the polls against his Republican upstart challenger, Indiana state Treasurer Richard Mourdock.  A while ago, Lugar held a double-digit lead over Mourdock; his lead is now down to 6 points (45-39).
