Edwards won't quit: "The oil & drug companies have had 7 years of a pres. who stands up for them. It's time we had a pres. who stands up for you."

"The oil companies, the drug companies, have had seven years of a president who stands up for them. . . . It's time we had a president who stands up for all of you."

Sorry 'bout that. It wasn't John Edwards after all. It was Hillary in a TV spot in Wisconsin she began airing yesterday.

The Wall Street Journal notes:

As the Democratic presidential contest moves to the distressed industrial Midwest, Hillary Clinton and Barack Obama have ratcheted up their antitrade, anticorporate rhetoric.

The candidates have made broad attacks on corporate wealth and tax cuts they say tilt toward the rich, along with more specific attacks against health insurers and oil companies, among other industries.

Both candidates increasingly sound like former North Carolina Sen. John Edwards as they pursue his endorsement and the voters -- particularly union members -- who were drawn to the populist candidate before he dropped out last month. Illinois Sen. Obama got a boost toward that goal Friday with the backing of the Service Employees International Union, one of the most politically powerful labor organizations.

One factor in the endorsement is the North American Free Trade Agreement, signed into law by President Bill Clinton in 1993 and blamed by many unions for sending jobs to Mexico. Sen. Obama has increasingly hit Mrs. Clinton on Nafta.

Business groups are dismissive of the Democratic attacks. "They should be talking about ways to grow the economy such as deregulation and lessening burdens on employers, rather than criticizing them with simplistic politically driven rhetoric," said Randel Johnson, a vice president at the U.S. Chamber of Commerce.

SEIU's backing came on the heels of an Obama endorsement Thursday by the United Food and Commercial Workers, which has 1.3 million members. Overall, though, the labor movement remains divided between the two candidates. Mrs. Clinton has far deeper support from unions representing government workers, teachers and machinists, among others.
