You do realize the Tories are way to the left of the GOP on the political spectrum, don't you? Can you see a GOP president (bear with me, this is hypothetical) or GOP majority leader in Congress proposing a same-sex marriage bill, let alone getting it enacted as law?
Oh, and guess who the Tories hired for their campaign team? None other than Obama campaign chief, Jim Messina.
Nice to see you leaning to the left though.British Conservatives: Not Very Conservative By U.S. Standards
