Judge Carter dropped the Obama eligibility case because he believes that his court could not remove the President if it found that he was not eligible. He said that it is up to Congress to get the job done.
Congress will probably not take those steps, even if we vote good conservatives into office. It's just too much controversy for them politically. We'll just have to make sure to vote him out of office.
A bright spot, though, 3 states have on their ballots bills that would require any Presidential candidate, including an incumbent President, to show actual birth certificates and prove eligibility to be able to be on the ballot.
