They like him because they don't know any better. If Kennedy were around today he'd be about as conservative as John McCain.
In other words not at all.
I meant the late John McCain. Chris Christie would be another good comparison or Romney. Kennedy would be a moderate to conservative Republican today.
Kennedy was an opportunist, and would be whatever would get him the most media adulation. Like his brothers he would have effortlessly glided from conservativish Democrat to ultraliberal, a process that was of course already ongoing at the time of his death.
And, McCain has never been a conservative, unless you count his time in the House of Representatives and his first couple years in the Senate.
In 2008 it took McCain a few months, but he finally became a conservative on things he wasn't in the past. He began supporting arctic drilling and tax cuts which he voted against during the Bush Administration. Usually it's the other way around where candidates move to the middle to become more electable. What I like is that McCain didn't change back after the election but has continued to become more conservative since representing our party for president in 2008.
