Crimmins has said he is running because he wants to make a difference by encouraging economic growth and strengthening national security.
He is a retired military officer and a San Diego teacher with two master degrees in education. Crimmins is a resident of Point Loma. But if elected, he says, he would move to Imperial Beach.
Vargas, a native of National City, has pledged to work to preserve Medicare and Social Security benefits.
Vargas is a Senator in the State of California, 40th District and a former member of the California State Assembly.
He spent some of his campaign funds for the June 2012 primary on mailers to promote Republican Michael Crimmins, who finished second and edged out former Democratic state lawmaker Denise Ducheny for the right to face Vargas in the November 2012 election.
Both Crimmins and Vargas have said they look forward to a spirited race.
