President Donald Trump's effort to stack the Federal Reserve with ideological allies has run into a familiar foe: Republican Sen. Mitt Romney, who's likely to continue to act as a bulwark against the central bank becoming a target for political appointees.

Herman Cain's decision Monday to withdraw his name from consideration as a Fed governor was largely academic. Romney and three other GOP senators already were poised to torpedo the former Kansas City Fed president and pizza CEO's nomination if it was brought to a vote.

Romney and Trump have clashed before.

The battleground has now shifted, and Romney is expected to dig in against efforts by Trump to appoint Fed officials who will enforce his highly publicized demands for lower interest rates.

"On a lot of issues, Romney is sort of a Boy Scout. I think he sincerely believes in getting the best qualified people, and clearly Cain was not," said Greg Valliere, chief U.S. policy strategist at investment manager AGF. "Romney is going to try to be the arbiter of who's qualified and who's not. The friction between Romney and the White House is only going to intensify."
