Columnist Jim Callahan, writing in the West Chester Daily Local News, wonders if American voters are so fed up with Republicans that they would support the most liberal presidential ticket in perhaps 30 years.

National Review ranks Sen. Barack Obama as the No. 1 most liberal member of the U.S. Senate. The same publication, highly respected an nonpartisan, ranks Sen. Joe Biden as the No. 3 most liberal member of the Senate.

"Ever since the Vietnam War, being tagged a liberal in American politics could sometimes lead to trouble for a politician. Plenty survived, but many went down the chute," Callahan writes. "The suspicion here is that the Democrats don't think it matters anymore. The theory here is that Obama is reasoning that after nearly eight years of conservative Republican government under President Bush, the public is weary, and really does want change."

Democrats are fighting against history. There's a growing list of liberal Democratic Party presidential nominees rejected by voters: George McGovern, Walter Mondale, Michael Dukakis, Al Gore, John Kerry.
