Alan Keyes, a three-time Republican presidential candidate, called President Obama a radical communist and a usurper and said with him in charge, America is going to cease to exist.  He said that President Obama is not the president, is an abomination, not a citizen of the United States and thinks that the military of the United States should not take orders from him.   This shows you the state of mind of the Republicans.  Not all of them are this nutty but many of them share some of his views.
