Quite simply, Roy Blunt has been too closely tied to Tom DeLay, to deeply involved in the "K Street Project," too intimately associated with Jack Abramoff, to be an effective Majority leader. The die has been cast; the whiff of corruption that comes off the acting Majority Leader has taken on an overwhelming stench. He is literally in bed with a lobbyist for the tobacco companies...His wife is Abigail Perleman. (Mr. family-values divorced his wife of 35+ years in order to marry Ms. Perleman.)
Public Citizen has issued a 48 page full report, and a 9 page executive summary.
UPDATE 10:44 pm, January 16: From my good friends over at Fired Up! Missouri:
Mr. Abramoff's Quid Pro Quo With Mr. DeLay And Mr. Blunt On The Guam Legislation - In 2002, Jack Abramoff was working to kill H.R. 521, a bill that would have reorganized the judiciary on the tiny island of Guam.
Mr. Abramoff's real client was the Superior Court of Guam, but for reasons as yet unknown, on his lobbyist disclosure reports, Abramoff instead indicated that his client on this matter was Howard Hills, a Los Angeles-based attorney.
Mr. Hills was also a donor to an Abramoff controlled PAC, NewStar PAC. This was a relatively small PAC, with only a handful of donors, and very strategic giving patterns.[See full post at Fired Up! America]
It seems that after contributing to Mr. Blunt's and Mr. DeLay's re-election funds, the bill Mr. Abramoff didn't like went the way of the dodo, so to speak. An up-or-down vote was never held.
And finally, here are some links to click to look into Roy's malfeasance yourself.
