Campaigning in a state where his party's stock is rising, President Obama warned Democrats not to take any race for granted in this volatile election season.
"There is no doubt this is a difficult election. This is a tough political environment," Obama told voters in Delaware, where Democrat Chris Coons holds a solid lead in the polls over tea party-backed Republican Christine O'Donnell.
Speaking on the stage of an ornate opera house, Obama said Coons shares the same values as the man whose old Senate seat he's running for -- Vice President Joe Biden, who joined Obama at Friday's rally.
With less than three weeks until the Nov. 2 election, Obama is on a campaign blitz, traveling coast to coast trying to raise money and generate enthusiasm for Democratic candidates trying to hold the party's majorities in the House and Senate. Obama's message: while the economy may still be struggling to rebound from the recession and middle class families are still hurting, he says the GOP only wants to return to the policies he says led to the economic crisis.
"It's not about the work we've done, but about the work we have left to do," Obama said.
