This is lighting up the interwebs, so let's discuss. It turns out the college grad gender split balances this almost perfectly. 
Currently, 56% of college grads are women. So in a dating pool of 100 post-college grads you'd have:
21 lib men
23 con/ind men
38 lib women
18 con/ind women
21 lib men
23 con/ind men
38 lib women
18 con/ind women
The conservative a somewhat evenly balanced--particularly since polls have shown they're more tolerant of people with different views.
The liberal women are in trouble. Roughly half of them will be unable to find a mate who mirrors their views. Bad news, especially since liberal women are far and away the least tolerant group.
This would suggest that ~30% of college educated Millennial women will end up childless, not so much by choice, but because their pickiness and whacky politics eliminate the possibility.
