Since when is the Youth vote against Hillary?
Polls are showing that she's doing better with olds for whatever reason.
She does well among those under 30, but above 30 we don't see the same age gradient with her that we saw with Obama. With Obama, there was a pretty clear trend with age, where the older age groups were his worst demographic. With Clinton, many polls have the 30-45 age group as her worst demographic.
Latest PPP national poll for example:
http://www.publicpolicypolling.com/pdf/2011/PPP_Release_4313.pdffav/unfav spread of HRC by age:
18-29: +39%
30-45: -6%
46-65: +5%
65+: +3%
In the matchups against Republicans though:
Christie vs. Clinton:
18-29: Clinton +32%
30-45: Christie +2%
46-65: Clinton +1%
65+: Christie +4%
Rubio vs. Clinton:
18-29: Clinton +35%
30-45: Clinton +1%
46-65: Clinton +7%
65+: Rubio +6%
