Democratic rivals John Kerry (search) and John Edwards (search) campaigned on opposite ends of upstate New York Sunday, two days before voters cast their ballots in the crucial "Super Tuesday" primary.

The two senators have focused most of their attention up until now in New York City since 70 percent of the primary votes normally come from New York City and its suburbs.

Kerry of Massachusetts planned a town hall meeting in downtown Buffalo where he will address economic issues. Edwards of North Carolina planned a jobs rally at an airport in Albany, about 260 miles to the east.

Independent polls have shown Kerry sporting a big lead over Edwards in New York. Edwards has virtually ceded four New England states to Kerry and stands little chance of victory in the biggest battlegrounds, New York and California, or Maryland.

Kerry, who picked up the endorsement of former New York Gov. Mario Cuomo (search) Saturday, won the backing of four newspapers in New York, which all cited Kerry's experience as the Democrats' best chance to unseat President Bush in November.

"Kerry's lengthier and more deeply grounded service in the Senate seems absolutely vital to a solid presidential candidacy," The Buffalo News said in its editorial published Sunday. "If the nation decides to change leaders this November, it should place the White House and America's future in experienced hands. Kerry best meets that standard."

The New York Daily News called Kerry "a sharp contrast to Bush. He is pro-choice, opposes the death penalty except for terrorists, favors gun control and would repeal the President's tax breaks for the wealthy."

Newsday wrote that Kerry "has proven himself" during his long record of public life.

Meanwhile, the Times Union of Albany wrote Kerry "has emerged as the most qualified Democrat running." The newspaper also wrote that John Edwards should top Kerry's list of possible running mates because Edwards "represents great promise for the future of his party."

A Kerry-Edwards ticket, the Buffalo News said, "would be formidable."
