It seems that if CBS only wanted us to vote once they would say so...I think they want as many votes as possible so they can say "and Kaysar got 1 million votes" so people will think the show is that popular....
To vote for Kaysar I select his button, vote, then go to the "America's Choice Vote" button on the right side of the orange bar above..that takes me back to a clean new voting screen...this is fast and I have voted 30-40 times so far..
