But the left’s brush is big enough to smear not only Palin, but the entire Tea Party movement, Glenn Beck, and others.
“Progressive Arizona Rep Gabrielle Giffords is shot. In her ads, Sarah Palin had her targeted in a gun site. Inciting to violence.” – Jane Fonda on Twitter 
“In addition to issuing the map with cross-hairs on it, Palin told her supporters on Twitter: ‘Don't Retreat, Instead-RELOAD!’” 
Additionally, within minutes of the attack, hard left-winger Paul Krugman of the New York Times asserted that the reason Giffords was shot was because her seat was not turned over to Republicans. Despite that no political motive was at all known, Krugman immediately asserted that it was the fault of the Tea Party and Sarah Palin.
As to Andrew Sullivan, on his DailyDish blog for the Atlantic, Sullivan posted an unconfirmed and anonymous claim from “a reader” who claimed to have heard people in a store callously saying that they were glad that a Republican could be appointed to replace the wounded Giffords. This “reader” also claimed that one of them said, “Well, that’s to be expected when you’re so liberal.” 
This horrific incident is being exploited for political advantage in a way that is devious and desperate. The left has a new opportunity to falsely blame their opponents for something for which those being blamed have zero responsibility. The media will repeat the lie often and loudly enough that some will believe it.
Let’s consider a few relevant points:
1. Political partisanship has always been part of our culture. It is the main reason that we are not already enslaved by people like Barack Obama. It has never been wrong to use metaphors involving targets, guns, etc. for political purposes. That is taken by only the mentally unstable as being anything other than a metaphor. It is not anyone’s responsibility to make sure that what they’re saying won’t send some insane or mentally unstable person over the edge. Anything might do that for someone. Our Constitution designed our political structure to be an adversarial system on the belief that this would help prevent anyone from gaining too much power. Otherwise, we would have one-party rule and a communist-type government.
2. Extreme rhetoric is not nearly as much a problem as the extreme political positions and actions of radical fascist-socialists in positions of power in the federal government. Right-wing and Tea Party responses to government have necessarily and rightly been loud and strong. Our freedom is at stake. But none of this is responsible for the violence. The shooter is.
3. The Obama Administration has been steadily working to reduce and eventually virtually eliminate freedom of speech, especially political speech that opposes them. They will seize upon this as an excuse to try to force people to make their speech more friendly to the government, and to crack down on guns.
4. The person charged in these shootings cannot be classified as a right winger or Tea Party type. He appears to be a lunatic with political beliefs that are simply weird. He likes the Communist Manifesto and Mein Kampf , for example, and does not seem to have made any political statement that makes any sense. His alleged crime is on the order of that of John Hinckley, Jr., who shot President Ronald Reagan, or Joseph Stack, who flew his plane into the IRS.
To try to link this crime to Sarah Palin, Glenn Beck, or the Tea Party, etc. is a disgusting display, and those who are doing it will not be successful. The American people (mostly) are able to see through this travesty.
Meanwhile, we express our sincere sympathy and offer prayers for all who have been hurt by this senseless and tragic event.
