Burris Denied Entry At U.S. Senate

I don't understand this...
Dems care SO MUCH about the constitution when it comes to people who try and blow up our country, why not now?
Why isn't this guy seated?
And even though this has nothing to do with race, you know damn well that if Republicans were blocking this guy the networks would be on 24-7 calling for the race card to be printed and given to every single US citizen.
