The real story here is that the voting machines are apparently racist.

Via the Obama Report:

President Obama visited the polling station at the Martin Luther King Community Center in his hometown of Chicago on Thursday to cast an early vote for the 2012 Presidential election. 

But the purportedly tech savvy President appeared to be befuddled by an ordinary, run-of-the-mill voting machine. Ultimately, an employee at the polling station came to the rescue, as he guided the President through the step-by-step process of using the typical, every-day, run-of-the-mill voting machine.
