I'm sure that Bush's compliant, lapdog media covered it up for him. </sarcasm> Had anything like this been going on during the Bush terms, we would have been hearing about it 24/7 for months on end.
In the 2000 presidential election, the 'Rats and their media buddies got some stories out claiming that black voters were intimidated in Florida. Florida, naturally, was the state where Gore's loss cost him the election. But no claims of that sort were ever backed up by evidence, to the best of my knowledge.
In 2004, they made some similar claims in Ohio immediately following the election, but again no substantial evidence was produced. Bush won Ohio with a margin so substantial that Kerry decided not to request a recount.
My guess is that's what Ms. Powers was referencing, as she reached for straws in attempting to compare the New Black Panthers with an alleged similar incident that was quashed in the Bush DOJ. In doing so, Powers was merely creating revisionist history, which is an old MO of the left.
