Katy Perry showed her unwavering support for President Barack Obama at the Las Vegas campaign rally last night.  Rocking the stage in a short and tight white dress with a 2012 voting ballot design on the front, Perry performed for about 10,000 supporters before President Obama took a moment to address the crowd.
