The Republican Party's opposition to all things Obama has earned it the nickname "the party of 'no.'" But the GOP is betting that its opposition will attract voters concerned about deficits and unemployment. "We're the party of know: k-n-o-w," said Rep. Pete Sessions, R-Texas, chairman of House Republicans' campaign committee. GOP strategist Vin Weber sees no downside to "no" votes. "The basic rule is you rarely pay a price at the polls for being against something," he said, though he acknowledged, "that's quite aside from whether you should or shouldn't, or whether the country needs it or doesn't need it."
