They are already demonstrating against Obama in Keene, NH, because he reneged on his promise immediately to pull the troops out of Iraq.
The demonstrators in Keene are still brandishing “IMPEACH!” signs, but now that Bush is only 12 days away from leaving the Presidency, I can’t imagine what those signs mean, unless they are targetted at Obama.
Obama probably wanted Bill Ayers as his Vp but knew that would guarantee his followers would demand his impeachment so Ayers could ascend.
