The NRSC has been trying to run damage control by tieing Abramoff to Democrats, but it's not technically true. Some of Abramoff's clients made contributions to Democrats, but he has never PERSONALLY given money to a single Democrat. All of his personal and family contributions went to Republicans.
I don't think Americans care too much about this issue, however, so it would probably be better for the GOP to remain silent than try to counter with mistruths.
Like others have said, this will likely yield a new era of bipartisanship (for the cover up).
Then again, the Dems have less to loose since the MSM will shill for them.
