Yes, abortion isn't going anywhere. Gay marriage and birth control will need to go if they want to win a presidential election anytime soon. What would a Huckabee independent run look like in 2016?
Probably something like this?
Clinton/Warner 42.5%
Paul/Walker 36.5%
Huckabee/Palin 21.0%
Really? You think a
HUCKABEE/PALIN ticket would attract a non negligible amount of Democratic support?
Almost all of his vote share would be coming from otherwise Republican voters. Unless you're assuming Hillary would lose to Paul 57-43 as a baseline, which is even more ridiculous. Huckabee would also not do nearly that well. In fact, I doubt he'd win a single state, though he could potentially snag second in a few like Perot did.
If Huckabee is more of a Nader-like annoyance than an actual contender (ex: he wins 3-5%) Hillary would still probably crack 400 EV due to him siphoning away Republican votes in key states: something like 52D-43R-4I in the popular vote).
If Huckabee is more of a Perot-like (or better) contender, Hillary would probably win over 500 EVs. (51D-25R-23I).
