So much; frankly unavoidable even without those two since Gore was a pretty stiff dude himself. W was clearly the last appealing Republican nominee for young people, especially in 2000.
Gore shouldn’t have picked Lieberman and doubled down on this anti-youth persona, however. Kerry/Edwards did a much better job appealing to youths and the exit polling tends to show this too.
At least Bush was sort of libertarian on video games and other youth issues. There is a strain of 'boys will be boys' sentiment in the Republican party, while there is a nanny state Karen strain in the Democratic side.
