Wealthy former congressman Darrell Issa says he retired from the U.S. House of Representatives because the Southern
California district he served for 18 years had grown too moderate and no longer fit him.
With his name recognition and wealth, Issa's entry Thursday into the race in the 50th District increases the pressure on six-term Rep. Duncan Hunter to step aside, analysts say.
Hunter was one of the first to endorse candidate
Donald Trump before the 2016
election, but political analyst Carl Luna said Issa's bid sends the message to voters that the
Republican party does not want to take a risk.
