Rubio would have won it against Hillary. Trump probably loses it, but not as badly as Romney, largely because the current 18-24 crowd is somewhat more conservative than the previous one.
LOL no. Youth turnout was down in 2012 from 2008, and IIRC, although Romney did win younger white voters, the younger generation is increasingly more diverse, and of course this bodes well for Democrats.
Young people aren't going to vote for a party that they already think hates women, minorities, gays, Muslims, etc. *insert Trump's comments here*
Young people have New York values, to quote your candidate.
