"Three United States District Courts have ruled that private citizens do not have standing to challenge the eligibility of candidates to appear on a presidential election ballot: Robinson v. Bowen, 567 F. Supp. 2d 1144 (N.D. Cal. 2008); Hollander v. McCain, 2008WL2853250 (D.N.H. 2008); Berg v. Obama, 08-04083 (E.D. Pa. 2008)."
There is a HUGE difference in challenging the right for someone to RUN for president, versus challenging their right to BE president. These prior rulings DO NOT APPLY now that Barack Obama has been elected. Assuming the challenges have been changed from RUNNING for president to BEING president, it should be a whole new ballgame in the supreme court.
