well more importantly - he's not going to win. Even if the Democrats take back the White House, he's not going to be the guy. I's going to be Dean, Edwards or Kerry. Ergo, he's just another stuffed shirt trying to get some attention.
Plus, remember Lieberman is the guy who headed up those senate hearings in the early 1990's. However, we had Tipper Gore's husband in the White House for eight years and music censorship didn't become a huge deal, so I don't care what Lieberman says right now - it won't make a difference.
It is hilarious, though, that GTA3/GTA:VC were released
years ago, but they don't make a big stink until an election year. Remember that.
