Please tell me you're kidding. You think the left has cornered the market on smears and slander? Do you live under a rock or are you just so partisan that you can't see what's out there every day from the right? Please - according to the right, the president is:
not a citizen
a muslim
pals around with terrorists
is a marxist
a socialist
a nazi
is trying to destroy the country
etc., etc., etc.
And don't even get me started on the crap the republicans pulled when Clinton was in office.
