If you want to follow it, then get your congressman to start the impeachment process or pick a candidate for 2012 and start working for them.
If not, then file a bunch of these stupid lawsuits.
How about doing all of the above? Plus getting laws in place to require proof of eligibility for his and all offices.
But you see before there can be an impeachment, if one is even possible, there must be an investigation. The birth certificate must be subpoenaed and constitutional scholars consulted on the meaning, for purposes of eligibility to the Office of President, of the term "natural born citizen". You think the Democrats in Congress are going to allow that? I don't. Without their permission there would be no power to subpoena the birth certificate, or to get the scholars to testify to Congress. So that leaves the courts.
BTW, I'm not one is 100% certain that he not a natural born citizen. But I'm not 100% certain that he is. I think the American people deserve to know, one way or the other. After that, let the chips fall where they may.
