A Team Romneyite e-mails:

In 2006 – McCain’s was 65%. A year when he knew he was running for President. It gives you a pretty good idea how he would govern.
He was wrong on tax relief (voted for a 60 vote supermajority in order to provide tax relief); wrong on the Federal Marriage Amendment; wrong on immigration and border fencing; wrong on embryonic stem cell research funding (he has repeatedly voted for).
It is not the lifetime rating that matters – it is where he is now – and it is not conservative – his rating is comparable to Senator Ben Nelson – a moderate Democrat.
Remember even moderate Republicans voted for the President’s 2001 tax relief – McCain and Lincoln Chafee were the only Republicans to vote against it.
