SAN DIEGO, Calif. - Another conservative leader, American Conservative Union head Al Cardenas, endorsed Republican Mitt Romney for president on Monday.
Following last week's endorsement from former Fla. Gov. Jeb Bush, Cardenas described Romney as an "honorable, worthy, competent, conservative candidate for our next commander-in-chief."
In an op-ed in the Daily Caller, Cardenas said he also hoped the primary process will be over as soon as possible. "Every week the primary continues," he wrote, "Republican chances for victory in November diminish because our sights are not set on our chief goal - defeating President Obama."
Cardenas likened the drawn-out primary to children in a car asking "Are we there yet?," and said none of the other candidates have enough delegates to realistically win the race.
Romney's campaign also announced on Monday the support of Sen. Mike Lee, R-Utah, and House Majority Whip Kevin McCarthy, R-Calif.
And in another sign that the Romney campaign is lining up endorsements from conservatives in the West, former Hewlett-Packard CEO Carly Fiorina also announced her backing on Monday.
“Mitt Romney's unique experience in both the public and private sectors prepares him best for the challenges that face our nation," said Fiorina, who lost her bid in 2010 to unseat Sen. Barbara Boxer, D-Calif. "As his track record amply demonstrates, he will focus on the real reforms we so urgently need in Washington and work to restore economic opportunity for all Americans."
