I really don't understand why Romney, Huckabee and Guiliani were so easy on McCain.
It's one thing not to sling mud and be cordial but the failure to hammer McCain on his immigration stance and for voting against tax cuts is mystifying.
McCain does look old, and you're right, he doesn't like it when his age is brought up. However, this is a delicate matter and is hard to use against him, especially in a state like Florida with it's huge number of retirees.
I thought Huckabee handled the Chuck Norris/McCain age question very tactfully and humorously but had an opportunity to say something like 'McCain isn't too old
right now, but in any event his record on immigration is so horrible he should be disqualified as a serious candidate even if he was 50 years old instead of 128'.
OK, that might have been a little too harsh
but you get the idea.
As far as the New York Times endorsement of McCain goes, conservatives hate that rag, and that will only hurt McCain, not help him.
Anyway, although McCain didn't harm himself in this debate, he was clearly outperformed by Romney and Huckabee, and hopefully will not win Florida.
