(CNN) - Mitt Romney is weighing in on competitive Republican primary for a GOP held House seat in California - the latest sign that the 2012 Republican presidential nominee plans to play an influential role in helping to shape the future of his party.
CNN has learned that Wednesday Romney will endorse Tony Strickland for Congress in California's 25th district, to succeed longtime GOP Rep. Buck McKeon. The House Armed Services committee chairman announced in January that he wouldn't run for re-election this November.
Strickland is a former California state assemblyman and state senator who represented parts of the traditionally Republican leaning congressional district, which is located in northern Los Angeles County and includes Simi Valley (home to the Ronald Reagan Presidential Library) and the city of Santa Clarita. Strickland, who's been endorsed by McKeon, is one of a half a dozen GOP candidates running in the June primary.
"An experienced legislator, a devoted husband and father, and a longtime community leader, Tony Strickland is exactly who we need in Congress. Tony led the fight against the Democrats' excessive budgets in Sacramento and worked to bring California's crippling deficit under control. He will do the same in Congress," wrote Romney in a statement acquired by CNN.
"Tony will fight to limit government spending and support economic policies designed to create jobs. He knows we cannot pass this unsustainable debt on to future generations, and Tony will face this problem head on so we can leave a stable, debt-free country for our children and grandchildren," Romney added.
The endorsement doesn't come as a surprise, as Strickland served as California co-chairman of Romney's 2008 and 2012 presidential campaigns. Romney has already made a donation to Strickland's campaign.
Romney's new political role
Romney's backing of Strickland comes one day after he endorsed state lawmaker Andy Tobin in the Republican primary for Arizona's first Congressional District. The Arizona House Speaker was a supporter of Romney's 2012 White House bid. And it comes one week after Romney starred in a television commercial put out by the U.S. Chamber of Commerce in support of Rep. Mike Simpson of Idaho, who faces a fierce primary challenge this year from a tea party backed candidate. Simpson was an early backer of Romney's last presidential campaign.
Romney looked and sounded very much like a candidate for office in his ad for Simpson. But the former Massachusetts governor has ruled out another campaign for president. Instead, he appears to be campaigning for another role: a party elder.
Romney stayed far from the political spotlight following his bruising November 2012 election defeat to President Barack Obama. But starting last spring when he hosted a summit in Park City Utah of some major political and business leaders, and last summer, when he headlined a fundraiser for the New Hampshire Republican party, he's been getting more and more involved in shaping the future of his party and guiding the national conversation.
So far this cycle he's endorsed or donated money to nearly 20 candidates, many of the establishment favorites who backed Romney in his White House runs.
"By now endorsing GOP candidates who have stood proudly with him over the last several years, the Governor is sending a clear message that he remains an essential Republican leader in 2014," veteran New Hampshire Republican strategist Jim Merrill told CNN.
With the two living former Republican presidents, George W. Bush and his father, George H.W. Bush, both staying far from the political conversation, Romney has begun to fill the void.
"Mitt Romney is the most prominent and engaged elder statesman the GOP has on the national stage right now," added Merrill, who was a top adviser to Romney in the Granite State in his 2008 and 2012 presidential campaigns.
Merrill said that Romney's "hard work on behalf of the Republican Party, whether through dissecting the President on Obamacare and foreign policy or aggressively fundraising for party committees across the country," is greatly appreciated.
But some grassroots conservatives don't share that view.
"Is the GOP stuck on stupid? Why does the Republican Party listen to losers?" asked Judson Phillips.
The Republican Party has listened to the Romney wing of the party and what has the result been? The GOP has lost the popular vote in five of the last six elections. If the GOP listens to Romney, it will be six out of seven," added Phillips, founder of the Tea Party Nation, a national tea party group. "Romney needs to go quietly into retirement. Let him spend time with his wife, his kids and grandkids but stay the hell out of the Republican Party."
