At least one state court (the Indiana Court of Appeals) was presented this issue by citizens who sought to have Obama's (and, oddly enough McCain's) electors ruled ineligible. The Cout's decision was cogently written and is worth your reading (unless, of course, the State of Indiana is also a party to this grand conspiracy). Google on something to the effect of "Steve Ankeny and Bill Kruse v. Governor of the State of Indiana".
“The Constitution makes Congress, not the federal courts, the judge of the presidential election.”
President Al Gore certainly agrees with that.
