California Republican Rep. Darrell Issa is retiring, just three months after declaring, “I can hold this seat. I’m not quitting.” The car-alarm magnate considered one of the wealthiest members of Congress says in a statement that "it's the right time for a new chapter and new challenges." Issa’s abrupt reversal injects more uncertainty in the race for Southern California’s 48th District, which was drastically reshaped in November after voters approved a new U.S. House map for California to favor Democrats. With another incumbent out of the running, it also increases the uncertainty around the ability of Republicans to hold the party’s fragile House majority.
