(CNN) - Just when you think you’ve heard everything in this race for the White House, along comes something truly surprising. Such was the case on Thursday's American Morning. I was speaking with former Massachusetts Gov. Mitt Romney about Sen. John McCain's new line of attack against Sen. Barack Obama. McCain hopes to paint Obama as a politician who puts party and self-interest above the needs of the nation, claiming that the Illinois senator has “never been a part of a bipartisan group that came together to solve a controversial issue”.
This morning, Romney faithfully repeated that charge. When I pointed out that Obama reached across party lines to work with Sen. Richard Lugar, R-Indiana, on a non-proliferation measure, and with Sen. Gordon Smith, R-Oregon, on increasing gas mileage requirements, Romney shot back, saying that “Actually, on both cases, you’re talking about two liberal positions, non-proliferation as well as the gasoline mileage."

It struck me as rather odd – having covered five years of the Bush administration as a White House correspondent – that the governor would view non-proliferation as a “liberal” issue. I seem to recall a little ditty called the “Proliferation Security Initiative,” launched by President Bush on May 31, 2003. The aim of the initiative is to enlist the nations of the world to “stop trafficking of weapons of mass destruction, their delivery systems and related materials to and from states and non-state actors of proliferation concern.” Whether the program is a success is very much in question (though the administration claims it is), but I’ve never heard anyone call it a “liberal” position.
