I completely agree with drjim, the rhetoric against sitting presidents by the opposing party has been ramping up ever since Newt and the Republicans went after Clinton. It got nastier and nastier throughout the Bush administration and now it ramped up even more with Obama. As for gun violence - the NRA does have way too much power, but so does basically every lobbying group from telecommunications to labor unions. Lobbying is easily the most toxic part of our politics on all sides. But the distinction in America is not the ease with which you can get a gun. Gun violence is worse here because nowhere else in the world are guns as cool and badass and manly and awesome and whatever....as they are here. It is a uniquely cultural phenomenon IMO.
