Example 1: Republican Congressman Compares Expanded Birth Control Access To September 11th, Pearl Harbor
Example 2: Rep. King Goes Birther: Suggests Obama’s Parents Telegrammed Fake Hawaii Birth Announcement From Kenya
Example 3 (another Steve King bit of buffoonery): Steve King Defends Dog Fighting Comments In Bizarre Diatribe
Example 4 (Newt endorsing Bachmann insanity which has led to threats of violence against an innocent woman): Gingrich Explicitly Defends Bachmann’s Attacks On Clinton Aide Huma Abedin: ‘It’s Totally Legitimate’
Those are easy examples, just from Think Progress.
