Looking at the way that those under 30 vote, I don't see how you could argue that it's the Democrats who are doomed. I don't buy the whole "mid-90s kids will vote Republican." It's not really backed up by any evidence.
In the short term, the real argument is 1997-2005 kids will vote 55% Republican.
Yes, the most diverse and liberal generation in history is going to vote 55% Republican. Definitely.
This generation is only more socially liberal, but not even in the progressive sense. Only in the libertarian sense. In some ways, this generation is more conservative than the last generation. They lean more republican than most people think. I for one see it because I am a millenial.
I don't see it at all. You're basically saying that Millennials are more libertarian (a laughable notion at best) because you, as one Millennial, happen to have anecdotal evidence that since you're a libertarian, our generation as a whole is more so.
This is simply incorrect and doesn't align with the actual polls and ground facts on the matter. There's no rising tide of libertarianism coming from this generation.
