Hi Funked,
I'm not about to shill for Allen, but if that level of gaffe was grounds alone for kicking out a Senator, then every one of them would be gone by now.
I think Tim Graham summed up the difference in how much attention the Allen gaffe is getting well:
In early July, Sen. Joe Biden joked before a C-SPAN camera that “you cannot go into a Dunkin Donuts of a 7-Eleven unless you have a slight Indian accent.” Conservatives had a little fun with it, but said: a harmless slip, but if a Republican ever did it, the media would have a much different standard. That day is now. Sen. George Allen mocked an Indian-American Democratic volunteer as a "macaca," and the Post played it up on the front page, along with a very tendentious staff editorial to boot insisting Allen's racial "bullying" was beyond "the bounds of decency." Washington Post coverage of Biden? None. Not in the paper.
