I grant you McCain had a decent conservative voting record.
Stable and sane is a whole different issue.
I would actually vote for Hillary before McCain.
At least with the Hilderbeast, you know what you are dealing with, she will stab you in the front, then rip you heart out.
McCain will stab you in the back, then rip you guts out.
Who would you rather have choosing your next 2 Supreme Court justices...?
