The time to challenge President-elect Obama’s citizenship has long since passed. Based on long-standing principles of election law, opponents must raise defects in nominating petitions, including the eligibility of the candidate, at the time of the filing of the nominating petition. Petitions were filed in late 2007 and early 2008. There were no legal challenges And not for nothing: Don’t you think that Senator Clinton would have raised this issue in order to keep BHO off the ballot? Citizenship will remain as a political issue, and may return as a legal issue in 2012.
