...I doubt that right wing elements will ever assassinate another president.
Wow, I don't know how you can go THAT far. I think we've seen more than enough arrests in just the last couple of years to demonstrate that the Becks, O'Reilly's, Limbaughs, Coulters, etc. of the nation have wound up enough whack-jobs, have utterly convinced them of so many ridiculous things about Obama - from his being foreign-born, to his actively hating America, to his agenda of bringing down the country - that there are MANY individuals and several ad hoc groups out there that would be proud to do the deed.
True enough, most if not all are as ill-equipped and incapable as to be comparable to me declaring that I am headed to New York to meet Rachel Maddow, lure her into abandoning her sexual identity, falling in love with me and pleading with me to marry her.
But unlike Rachel and I, all they need is an unexpected break - a momentary lapse, or an unanticipated attack. Moreover, as we've seen with other nuts in the very recent past, getting away cleanly and unharmed may be a lot more than they're hoping for or care about, if the goal is to "Save the USA."
I confess I am VERY concerned about Obama campaigning and coming into a lot of contact with "the public" over the next 15 months.
It doesn't take the well-organized, well-funded sinister roots of the corporatist RW to pull it off.
