Mike Huckabee's style is so unbelievably sickly-sweet - and I mean unbelievably in both the figurative colloquialism and literally; unbelievable.
His simpering, wheedling tone of speech is over the top. His genteel manner is over the top. His non-threatening "look-at-me-I'm-not-like-them" shtick is over the top. His "not-enemies-just-wrong" shtick is over the top, his perpetual assumption of the best Leftist intentions is over the top.
Everything about this guy screams fake-fake-fake. I wouldn't trust him to mow my lawn.
Now he wants to run up against Rush Limbaugh? News flash, Huck: Many men much better than you have tried and failed, or have succeeded only in creating a niche for themselves without harm to Rush. You'll either flop on your face, or you'll garner enough share of milquetoast anti-abortion liberals to stay afloat. But don't fantasize that you'll somehow provide an alternative to Rush, and that people will tune him out and tune you in. That would be utterly delusional.
