You mean there’s no difference between Hillobama and McCain on Iraq? On abortion? Still plenty of reason to care.
I don’t think that McCain would have any influence at all on the abortion issue. Lots of people assume that one or more court justices are going to croak in the next 4 years, but that’s not a given.
If there was a president Hillary, I don’t think she’d find it that easy to just pull the troops out immediately, which is why she’s backtracked about it before.
On immigration, Hillary would probably do exactly what McCain wants to do—open borders, everybody’s legal, ain’t I great?
So, while they aren’t the same people, I think it’s a wash as far as the results are concerned.
