The party breakdown is:
Democrats 45%
Republicans 36%
Independents 18%
Christie actually destroys Clinton among Independents, leading 47%-17%, but that leaves a lot of undecideds, and the total number of Independents isn't that great. Clinton still leads by 1 point overall, because of the large number of Democrats, and the fact that she consolidates Democrats behind her better than Christie consolidates Republicans.
Age breakdown of Christie vs. Clinton:
18-45: Clinton +9
46-65: Christie +1
65+: Christie +11
Age breakdown of Paul vs. Clinton:
18-45: tie
46-65: Clinton +2
65+: Paul +11
Please do not talk about Party breakdown after 2012, sir.
