OK, so...
1) Kerry votes on s*** for ~16 years
2) Zell Miller comes in and, in 2001, says Kerry has done a good job
3) For 3-4 more years, Kerry and Miller vote similarly
4) Zell Miller, in 2004, criticizes Kerry's voting record
So either Miller was completely full of s*** in 2001 when talking about Kerry's record up until then...or he's a hypocrite for bashing Kerry's moves the last few years which match up with his.
