That's actually true.
Every year, millennials become less and less white.
However, white millennials continue to vote for the GOP.
2012 - White Males 18-29 - Romney 55% - Obama 41%
2012 - White Females 18-29 - Romney 49% - Obama 48%
2012 - White Males 18-29 - Romney 55% - Obama 41%
2012 - White Females 18-29 - Romney 49% - Obama 48%
Looks like they are voting for HERESY to me!
