Former South Carolina Gov. Mark Sanford's brief challenge to President Trump has ended.  Sanford, who had announced his campaign for the GOP nomination in early September, said Tuesday that he was suspending that effort. 

Sanford was averaging less than 2% in limited national polling.  Former Massachusetts Gov. Bill Weld and former U.S. Rep. Joe Walsh remain in the race, but are also seeing little traction against an incumbent president who enjoys broad support within the Republican party.
