President Obama's re-election campaign is zeroing in on Republican presidential front-runner Mitt Romney more than ever.
In a theme the Obama campaign is increasingly emphasizing, Vice President Joe Biden says Romney is "a little out of touch" with Middle America.
Speaking on CBS's Face the Nation Sunday, Biden said Romney opposed the auto industry bailout and the national health insurance law.
"Everywhere I go in the country, there's millions of people out there that are benefiting now," from the law, Biden said. "There are those people with chronic diseases like cancer that don't have to worry about getting a phone call saying, 'You're cut off. Your insurance has run out.' ...And what is the Romney answer? There's nothing. All they argue is, 'Cut. Get rid of that.'"
Other Democrats have derided Romney recently for saying his wife drives two Cadillacs and for declaring that he understands sports fans because he is friends with the owners of several teams.
On foreign policy, Secretary of State Hillary Clinton told CNN Sunday that Romney's comment that Russia is America's No. 1 geopolitical foe demonstrated "dated" thinking that ignores the end of the Cold War and overlooks the current state of world politics.
For his part, Romney is concentrating on rolling out endorsements from prominent Republicans in an effort to demonstrate that he is moving inexorably to winning the GOP nomination. Among those who have backed Romney in the past few days are former President George H. W. Bush, former first lady Barbara Bush, former Florida Gov. Jeb Bush, Florida Sen. Marco Rubio and Wisconsin Rep. Paul Ryan.
Wisconsin holds its crucial presidential primary Tuesday, and Romney holds the lead there. Romney is ahead in Maryland and Washington, D.C., which also hold primaries Tuesday.
Campaigning in Wisconsin, Romney said Obama is building a "government-centered society" that is at odds with traditional American skepticism about government. He said Obama's healthcare law is a prime example of federal overreach.
Romney, the former governor of Massachusetts, has twice the number of nominating delegates as his closest competitor, former Pennsylvania Sen. Rick Santorum, according to the Associated Press. Former House Speaker Newt Gingrich and Texas Rep. Ron Paul are far behind in the delegate hunt.
