(CNN) - Is Mitt Romney's VP stock rising?
John McCain's campaign has remained tight-lipped about its vice presidential vetting process, but the Arizona senator appeared to suggest Monday night his former rival would make a very effective running mate.

"I'm appreciative every time I see Mitt on television on my behalf," McCain said at a fundraising event in New Mexico. "He does a better job for me than he did for himself, as a matter of fact."
Watch: Romney promotes McCain
There's no denying the former Massachusetts governor is angling for the No. 2 position on the Republican presidential ticket. He said back in March he would be "honored" to take the position and has been a constant fixture on cable news shows over the last several months - vigorously promoting the Arizona senator's candidacy while sharply criticizing that of Obama.
Just last week the onetime Republican presidential hopeful said Obama "looks toward Europe for a lot of his inspiration” after the Illinois senator suggested Americans would benefit from knowing more languages.
“I think John McCain is going to make sure that America stays America,” Romney said in an interview on Fox News.
Romney has long been considered a leading VP contender, despite engaging in a bruising and at times nasty primary fight with McCain. The economy has solidly become the dominant issue this election cycle and Romney, who founded the investment firm Bain Capital, brings a sterling business resume - particularly to a candidate who has admitted he lacks knowledge about economic matters. Romney is also a native of Michigan, and could given McCain the edge in that crucial battleground state that the Democrats won in 2004.
