In the United States you may not actually be able to buy votes but money does but you marketing and marketing has been proven to win elections. Considering this fact it appears as though Obama is sitting pretty with $81,761,012 at hand. Romney comes in a very distance second with $19,916,126 and the good Dr. Paul comes in at a an even more distant third with $3,761,886 at hand.
If money can buy elections Obama has this one in the bag… sadly.
