Widespread corruption in US election

The Guardian reports on the widespread corruption and "technical problems" which are alleged to have affected the recent American congressional elections:

The former first daughter Chelsea Clinton ran into polling trouble. Senator Clinton told reporters Chelsea had been turned away at a Manhattan polling site because her name did not appear in a book of registered voters. Investigators determined that her name had been sent to the wrong polling location, so she was unable to vote in the polling booth. She was offered an affidavit vote, which is similar to the provisional ballots used in other states.
In the very tight Virginia Senate race, the FBI said it was looking into complaints that callers had tried to intimidate or confuse voters in the contest, which pits the Republican George Allen against Jim Webb, the Democrat challenger.
The state board of elections secretary, Jean Jensen, said her office had forwarded several reports to the FBI of voters receiving phone calls intended to discourage them from voting or directing them to the wrong polling place.

Meanwhile, in Tennessee, our friend Ginny reports that she was also prevented from voting. Not only were her family, all of them Bush supporters, unwilling or "unable" to drive her to the booths, but there seem to be no provision to get blind people, and those with other disabilities, out to vote. I wonder why?

(Also, you might read her entry on overhearing a reference to "Obama bin Laden" at work recently. Not only are Barack Obama and Osama bin Laden obviously two different people, the former is not even a Muslim.)
