AFAIK, there were no similar questions regarding Bush. It’s a well known fact that ZER0 has not proven his eligibility. Active duty officers take “an Oath to Protect and Defend the Constitution from all enemies, foreign and domestic.” This soldier is basing his case upon the “enemies .. domestic” in the lawsuit.
As I said earlier .. it would be nice if instead, a well-heeled CIVIL organization or two would bombard the Courts with eligibility cases.
All of the relevant Constitutional officers of the Republic, including President of the Senate Richard Cheney of Wyoming, have affirmed Obama's eligibility and have certified his election in a proper and constitutional manner.
Until they are shown to be wrong, he is the perfectly legal President and C-in-C, and this soldier is (and should be) in deep doo-doo.
