Oh come on now. Be serious. You actually believe that we DH supporters are bigger bullies than the folks who can't wait to jump into a Hunter thread with "he can't win," "you people are delusional," "he's only at 1%," etc.? You and me both should be praying that our country's future isn't in the hands of people who would discount a candidate because some of his supporters were mean to them. That sounds like the touchy-feely party of Bill Clinton to me.
As for complaining about the tone of the arguments, how about setting an example by offering an insult-free, reasoned argument as to why you believe Duncan Hunter can't or won't win. Then I challenge you to respond point-by-point to a reasoned counter-argument as to why he can, given certain circumstances (see, few if any DH supporters are as sure that he will prevail as you are that he can't/won't; we see too much volatility in both parties to make such predictions).
Go ahead, take a shot at it.
