(CNN) – His loss last November hasn't quelled Mitt Romney's worries the country is headed in the wrong direction, the former presidential candidate said in a radio interview Wednesday.
"I'm very concerned about the country," Romney told radio host and comedian Dennis Miller. "I wouldn't have gotten into this if I thought everything was going swimmingly. And I'm still concerned about the country."
Since losing to President Barack Obama in last year's presidential vote, Romney has kept a low profile. He emerged for his first public remarks this month at a gathering of conservative activists in Washington, and also joined the board of his son's private equity firm. In June he'll host a policy retreat in Park City, Utah.
In his speech, Romney hinted he would remain a part of the Republican Party's efforts going forward, saying, "I am sorry that I will not be your president, but I will be your co-worker and I will work shoulder to shoulder alongside you."
He reiterated that point in his interview Wednesday.
"I keep looking for the most effective way to get the country on the course of remaining strong and powerful in terms of our values, our military, our soft power, our economy," Romney said, admitting he felt a certain "frustration" at his diminished role.
"Obviously I don't have the influence I would have had if I had won that election," he said.
But in other ways, Romney said life as the loser of a presidential election suited him.
"I have to admit, being able to go back to our own life, going to the grocery store, shopping on my own, is kind of nice to do by myself, without a bunch of people hanging around with me. So I like the life of being an American citizen. It's good to live a normal life again," he said.
