I wouldn't call him a bigger RINO than McCain, but they are both pretty offensive and were the first two on my "I will never vote for" list, followed closely by your tagline namesake, who is simply McCain light.
Hunter lost all credibility when he did that. He's a loser.
Now that is sad! Trust me, I was not thrilled when he endorsed the Huckananny. I would have preferred he abstained from endorsing anyone. He couldn't endorse Romney due to that Bain/3-Com/Huwei deal, (that got shut down, btw) or your tagline guy since his only pupose was to oust the conservatives, Hunter/Tancredo/Brownback, he certainly would not have backed Rudy for a number of good reasons and probably thought backing Alan Keyes wouldn't pull enough votes to keep McCain from the nomination. The way I see it, Duncan Hunter called for the original Operation Chaos by endorsing the Huckananny hoping for a brokered convention, or at the very least allowing folks to have a choice instead of the primary ending before it began.
However, to negate 30 years of outstanding service to his country as an Army Ranger in Vietnam and a Congressman that actually did good things and wrote some good laws, laws that were passed which many in CONgre$$ have never done in 40 years, simply because he verbally endorsed some guy?!?!?!
Did he campaign for him? Did he make ads for him? Seriously...give him a break!
Now you know how we former Fredheads feel every time someone tries to tie him to McCain.
