On the October 3rd, 2009 edition of Saturday Night Live, President Obama is mocked for being unable to follow up on any of his campaign promises of "change" that got him elected by a country fed up with politicians that don't keep the promises they make.
This reminds me of an old video from 2008 comparing the differences between Barack Obama and Ron Paul.
I doubt Ron Paul will run again in 2012. He could handle it (he bikes several miles a day and mostly eats salads), but his wife's heart probably couldn't. If he is convinced to run again one final time, he represents REAL CHANGE that would be quick and decisive. And he has a 35+ year record of saying the same things over and over again, as this video below demonstrates.
