re: Will Republicans fight to keep the next Democratic president from taking office?

There was nothing more unique about this election than many others.... no more so than a community organizer with perceived ties to radical Islam, and legitimate questions about his place of birth. Far more significant questions than what is being alleged at present against Donald Trump. Of course the birth certificate seems to have been produced and those issues laid to rest, but they were very real, after Obama's election. There was no concerted effort at that time to convince electors to change their vote. In the future I suspect there will be some escalating issue in every election.
