Same reason Nixon should not have debated Kennedy on TV.
Looks.
Every Udall ad I’ve seen in the several months has been his opponent is a woman hating mysogonist who opposes all abortion. He has no positives to stand on, he was the passing vote on Obamacare, he voted for the stimulus, he rubber stamped the entire Obama agenda, he opposed fracking in the state. It would be a very short odd debate if every single answer, is “my opponent hates women.”
does Udall have a big lead?
It only makes sense if you have a good-sized lead
Sort of like asking why crocs don’t chase things on the open terrain. Their forte is hide and spring, darting away before receiving damage. Libs do the same thing, hide behind various facades, lying about everything, looking like a regular human beings. Suddenly, they unmask and attack liberty and freedom, until the next election cycle, when they submerge and go into pretend mode once again.
