Would you make this same argument if Castro, Chavez or Ahmadinijad had been democratically elected president?
If Muslim immigrants managed to make Bin Laden the electoral winner, would you make this same defense?
The guys you name have all committed previous crimes that would make them ineligible to run in the first place. Nor - I think we can all agree - are they U.S. citizens.
But your analogy isn’t valid in any case. Guys like that never are democratically elected. And whatever else we think of Obama, he’s not a mass murderer; nor is he likely to become one. So can we knock it off with the hyperbole?
