While many on the conservative right have written off Gov. Mark Sanford because he has now admitted to having an extramarital affair, I personally don't think that's why he should resign and no longer be involved in politics.
Honestly what people do behind close doors is there business. There are things I do in my personal life other people might look down on. Profanity at times, drinking alcohol etc..... But as long as I do my job at work, my employer can care less.
While a politician is held to higher standards of course, I think as long as a person fulfills his or her duty in elected office he or she has done their job.
What I think should put a nail in his political coffin is the fact that his office whether through him on their own doing lied to his constituents about his whereabouts. Also the man used a taxpayer funded vehicle to drive to the airport to have his international affair.
Basically if he had not gotten caught this time he would have continued to lie and use taxpayers money to fund his affair. When you lie and deceive the very people who voted for you, then the hammer should drop.
Have your affair it's your business, but don't lie to me and don't use taxpayer dollars to commit adultery. When you are caught lying to the people you can never be trusted to serve the people's interest again. It's just the price you pay.
Here is how Mark Sanford's day looked like:
