Why has politics gotten so racial in tone?

Real simple answer is the left uses the race card so their guy doesn't have to take the heat. The opposition party is running scared of the false tag of racism. Let's see he was the bi-racial candidate, but he's the black president. It's real transparent,the socialists will do anything to keep power. How's that change working for you out there? How about all those new jobs? How about all that transparency in government? Sorry, he's just another slimeball that wants to suck every dime out of you, Only difference is,he's got a nice tan.
