From Clinton to Sanford and Weiner, here's what has stood out over the years.
Call it the Sanford-Weiner-Spitzer approach.
There are really two winners in South Carolina's special election.
If Weiner runs for mayor of New York, he would likely face more difficult challenges than Sanford did in South Carolina.
Partisanship and good old-fashioned campaign skill did the trick.
Few politicians have experienced the high and lows the former governor has been through in his career.
Berkeley and Dorchester Counties will be huge. So will the African American vote.
Outside group spending has favored the Democrat by more than 5-1.
Whoever wins today in South Carolina, it means nothing.
