Overdramatic leftist columnist Frank Rich flung wild charges at the McCain campaign from his Sunday perch in the Week in Review, accusing the campaign of "inciting vigilantism" on the trail while painting Obama as a potential victim of violent racism in "The Terrorist Barack Hussein [1] Obama [1]." 
If you think way back to the start of this marathon campaign, back when it seemed preposterous that any black man could be a serious presidential contender, then you remember the biggest fear about Barack Obama: a crazy person might take a shot at him.
....
"I've got the best protection in the world, so stop worrying," Obama reassured his supporters. Eventually the country got conditioned to his appearing in large arenas without incident (though I confess that the first loud burst of fireworks at the end of his convention stadium speech gave me a start). In America, nothing does succeed like success. The fear receded.
Until now. At McCain-Palin rallies, the raucous and insistent cries of "Treason!" and "Terrorist!" and "Kill him!" and "Off with his head!" as well as the uninhibited slinging of racial epithets, are actually something new in a campaign that has seen almost every conceivable twist. They are alarms. Doing nothing is not an option.
One wonders where Rich has been during the last eight years,in whichthe left-wing has reviled President Bush as a mass murderer, as Adolf Hitler, and as Satan himself, and spread conspiracy theories about hislying about the Iraq War, being responsible for 9-11, and letting blacks die in Hurricane Katrina...but some hotheads at a GOP campaign rally mark the dawn of a scary new era in politics? Please.
....what has pumped up the Weimar-like rage at McCain-Palin rallies, is the violent escalation in rhetoric, especially (though not exclusively) by Palin. Obama "launched his political career in the living room of a domestic terrorist." He is "palling around with terrorists" (note the plural noun). Obama is "not a man who sees America the way you and I see America." Wielding a wildly out-of-context Obama quote, Palin slurs him as an enemy of American troops.
The plural noun is noted: Palin was likely referring to Bernardine Dohrn, the wife of Bill Ayers - and cofounder of the Weather Underground.
It wasn't always thus with McCain. In February he loudly disassociated himself from a speaker who brayed "Barack Hussein Obama" when introducing him at a rally in Ohio. Now McCain either backpedals with tardy, pro forma expressions of respect for his opponent or lets second-tier campaign underlings release boilerplate disavowals after ugly incidents like the chilling Jim Crow-era flashback last week when a Florida sheriff ranted about "Barack Hussein Obama" at a Palin rally while in full uniform.
....
But we're not at Election Day yet, and if voters are to have their final say, both America and Obama have to get there safely. The McCain campaign has crossed the line between tough negative campaigning and inciting vigilantism, and each day the mob howls louder. The onus is on the man who says he puts his country first to call off the dogs, pit bulls and otherwise.
