SAN DIEGO — Carl DeMaio, a Republican, is a former San Diego city councilman and conservative radio host who recently led a campaign against the state’s gas tax.

He sat down with FOX 5 to speak about why he’s running for the 50th Congressional District.

When former Rep. Duncan Hunter stepped down over a corruption scandal, it left this sprawling district of northern and eastern San Diego County up for grabs. In the final month before the primary, a familiar Democratic rival and a trio of Republicans — including DeMaio — are the leading candidates to replace him.
