A senior Republican senator, speaking anonymously in order to freely discuss the tragedy, told POLITICO that the Giffords shooting should be taken as a “cautionary tale” by Republicans.

“There is a need for some reflection here – what is too far now?” said the senator. “What was too far when Oklahoma City happened is accepted now. There’s been a desensitizing. These town halls and cable TV and talk radio, everybody’s trying to outdo each other.”…

One veteran Democratic operative, who blames overheated rhetoric for the shooting, said President Barack Obama should carefully but forcefully do what his predecessor did.

“They need to deftly pin this on the tea partiers,” said the Democrat. “Just like the Clinton White House deftly pinned the Oklahoma City bombing on the militia and anti-government people.”

Another Democratic strategist said the similarity is that Tucson and Oklahoma City both “take place in a climate of bitter and virulent rhetoric against the government and Democrats.”
