Do your research, I shouldn't have to do it for you.
As governor he opposed the NRA, as presidential candidate he buys a life membership. As governor he supported the Brady bill, as presidential candidate, he opposes it.
As Massachusetts Senatorial candidate he supported marital rights for gay couples. As Presidential candidate, he opposes them. As governor he opposed a constitutional amendment to protect marriage, now as a presidential candidate he doesn't.
In 2005 he told the Boston Globe that McCain-Kennedy was "not amnesty." Now running against McCain he says it is amnesty.
His nickname is "flip-flop!" There is a whole litany of changed positions from when he was campaigning for office in liberal Taxachusetts, and now for office in the conservative GOP.
Just Google it. They are all there. Even on Youtube!
He is a fake and I will not support him in any way.
