Quinnipiac National Poll: Hillary leads Christie, Rubio & Ryan by at least 8

[Mr. Morden]

The crosstabs are consistent with PPP's polling in terms of the collapse of the age gap, and the fact that the GOP's strongest group now is the middle aged rather than olds.  Obama no longer being on the ticket seems to have caused a reversion to the 90s in terms of the age breakdown.

For example, in Christie vs. Clinton:
age 18-34: Clinton +18
age 35-54: Christie +3
age 55+: Clinton +12

And this basically holds for all the other matchups as well.  Doesn't matter whether it's Clinton, Cuomo, or Biden on the Dem side, or Christie, Rubio, or Ryan on the GOP.  The GOP is consistently doing better with the middle aged than they are with olds.

Also, the one demographic in which Rubio does slightly better than both Christie and Ryan: Hispanics.  Rubio wins 24% of Hispanics against Clinton, whereas Christie wins 23% of them against Clinton and Ryan wins 21% against Clinton.  Not much of a diff, but Rubio is doing worse than the other two in pretty much every other demo, so he's got to take what he can get.

Finally, it's also fun to look at how much bigger the gender gap is with Clinton on the ticket compared to Biden:

Christie/Clinton:
men: Christie +3
women: Clinton +19
gender gap = 22%

Rubio/Clinton:
men: Clinton +2
women: Clinton +28
gender gap = 26%

Ryan/Clinton:
men: Ryan +1
women: Clinton +24
gender gap = 25%

Christie/Biden:
men: Christie +6
women: Biden +1
gender gap = 7%

Rubio/Biden:
men: Biden +2
women: Biden +11
gender gap = 9%

Ryan/Biden:
men: tie
women: Biden +7
gender gap = 7%

Christie/Cuomo:
men: Christie +25
women: Christie +9
gender gap = 16%

Rubio/Cuomo:
men: Rubio +11
women: Cuomo +9
gender gap = 20%

Ryan/Cuomo:
men: Ryan +14
women: Cuomo +3
gender gap = 17%

Just looked at the crosstabs of this some more, and compared with the demographic breakdown of the 2012 exit polls.  It's clear that the gains that Clinton makes in "Clinton vs. X" as compared to "Obama vs. Romney" is in certain demographics (which overlap): white women, white Protestants, and voters over 55.  Those are the demos where Clinton is really overperforming Obama's showing in 2012.

I mean, for example, the 2012 exit poll had Romney winning white Protestants by a whopping 39 point margin (69%-30%).  But this poll has Christie winning white Protestants by just 16 points (49%-33%, which does leave a fair number undecided), whereas the overall victory margin for the Dems is only going up by 4 points.

Heck, even Biden basically matches Obama's performance among white Protestants, when pitted against Christie....despite doing 7 points worse overall.
