Republicans and Democrats jockeyed for economic high ground in a Labor Day warm-up to the Democratic National Convention , with Republican Mitt Romney labeling the holiday "another day of worrying" for too many Americans anxious about finding a job. Supporters of President Barack discounted hotels and costa rica Obama worked to put a glossy sheen on economic progress after offering discounted hotels and costa rica a more muddled message over the weekend.

"We've got our work cut out for us. We know that," he said. "The country is evenly divided. discounted hotels and costa rica It has been for a long time. So what are we going to do? This is going to be a working convention. Every one of you can sign up as a volunteer. In fact, I know you're already going to volunteer."
In Boulder, Colo., on Sunday, Obama warned a college crowd that "the other side is going to spend more money than we've ever seen in our lives, with an avalanche of attack ads and insults and making stuff up, just making stuff up."
"What they're counting on is that you get so discouraged by this, that at a certain point you just say, you know what, I'm going to leave it up to somebody else." Obama did not mention his own side's arsenal of negative advertising.
Younger voters gave Obama a big boost four years ago and he can ill afford to see their support drop off in a tight election where the sluggish economy is the dominant discounted hotels and costa rica issue in the nation and a specific drag to many young people coming out of college or trying to afford it.
But his campaign surely has a more immediate need for young people, too -- helping to fill the seats for Obama's address Thursday. With 6,000 delegates at the convention and thousands more attached to the event, Democrats hope to pack a nearly 74,000-seat outdoor stadium for the prime-time speech.

Keeping a strong focus on the economy, a new Obama campaign ad running in six closely contested states -- Colorado, discounted hotels and costa rica Iowa, New Hampshire, Nevada, Ohio and Virginia -- claims Romney's policies would "hit the middle class harder" and that he doesn't see the "heavy load" the middle class is carrying.
Biden joined the fray, accusing Republicans of seeking discounted hotels and costa rica to undermine the decades-old federal program millions of seniors rely on for health care. "We are for Medicare," he said. "They are for voucher care." That was a reference to a proposal in Congress by Wisconsin Rep. Paul Ryan, the GOP vice presidential nominee, to offer future retirees the option of buying health insurance with a government subsidy.
The president and vice president campaigned separately across three battleground states as delegates descended on the Democrats' convention city before their first official meeting Tuesday in the Time Warner Cable Arena.
Biden's itinerary, in particular, underscored the threat that a sluggish recovery and high, 8.3 percent unemployment pose to Democrats seeking another term in power. He was in Pennsylvania and Wisconsin, states that have received little attention previously as the candidates, their parties and outside allies concentrate on the areas of the country deemed most competitive. His presence suggested the race in both states was tightening.
Romney spent Sunday at his Wolfeboro, N.H., vacation home, leaving only to attend church services with his wife, Ann. Aides said he would spend much of the Democrats' convention week preparing for three fall debates with Obama, beginning on Oct. 3.
Obama aides said they expected Romney and Republicans to outpace the president and his party in fundraising in August because Obama spent less time raising cash than in the month before, and because the GOP held its convention -- usually a big money draw -- in August.
