Of course, I doubt most of that generation actually pay attention to news beyond something like the Daily Show.
Of course, I doubt most of the previous generation cared about anything except socialism and spending money worse than drunken sailors. There's more concrete evidence to my sweeping generalization than your's.
There's a much more obvious explanation. Republicans tend to be more uh... stodgy on social issues. Gays, moral stuff, women's rights, etc. Then there's the whole "hypocrite" issue. That IS really hyped by Daily Show, because it makes for great TV. It's easy to catch a politician saying one thing, and then doing another. It's not hard to find a true diehard GOP Republican that makes some morality or fiscal responsibility speech, and then catch him with a male hooker, solicitation a homosexual encounter in a public restroom, getting caught snorting blow/pills, or whatnot.
Dems just commit to wanting to blow money. Hard to claim a politician is being a hypocrite there. The rest are a basket of more niche concerns. Of course, the best hypocrit "sting" done by the Daily Show was on a union, which are little more than money laundering operations for the DNC.
