I have a better idea since you are the consumate expert on all issues. You tell us how he was a Conservative. You're arguing he is...prove it.
supported bans on abortions
Supported limits on family planning
Supported tax cuts for the wealthy
Supported rolling back regulations
Supported increasing defense spending
Supported right to work laws
Supported At Will Employment laws
Opposed gay marriage
Opposed the repeal of DADT
Supports Israel
Supports a war with Iran
Opposed the Affordable Care Act
Opposed the dream act
In short, every bit of RW batshittery out there, he signed on to it.
But there's more.
When he hired a gay man to be part of his Foreign Policy team, a conservative preacher demanded the guy be fired , and he was.
When Limbaugh called Fluke a "slut", the best Romney could say was "that wasn't language I would use". (There's a nice way to call a woman a slut?)
In short, Romney was everything the far right asked him to be. He didn't stray an inch from your dogma.
Now part of it is, your dogma has become so ugly that even I can't support it anymore. Had no problem with it even four years ago, when I held my nose and voted for McCain, but Romney didn't have McCain's principles... or even George W. Bush's.
