You citizens of the USA have probably by now heard about the comments made by Senate Majority Leader Harry Reid (D-NV) about then-candidate Barak Obama. Pretty much everyone says that Sen. Reid’s comments were "racist". Sen. Reid acknowledges that his comments were improper.
However, you also will recall, or have heard the story dredged up on the news a zillion times by now, that Sen. Trent Lott (R-MS) once praised late Sen. Strom Thurmond who once ran on a segregation ticket.
Just one story of many can be found here if you want background.
Sen. Lot was forced out of his position as Senate Majority Leader because he was charged with racist remarks.
Sen. Reid made self-admittedly racist remarks, but he is not being asked by his own party to step down as Majority Leader.
Here is a POLL question.
