Scandal-plagued District 4 U.S. House Rep. Scott DesJarlais defied expectations of a blowout defeat in his bid for a another term, instead emerging from the Republican primary with a razor-thin margin that left the race too close to call.


With all precincts reporting, Dr. DesJarlais and challenger Jim Tracy were separated by a 33-vote margin, illustrating the willingness of the incumbent's tea party base to overlook his personal problems that included once urging a mistress to seek an abortion.


The final result of Thursday's election may drag out until the end the month.
