TOLEDO, Ohio (AP) — 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 Obama worked to put a glossy sheen on economic progress after offering a more muddled message over the weekend.

Obama addresses a United Auto Workers Labor Day rally in Toledo before getting his first look at the aftermath of Hurricane Isaac in a stricken parish outside New Orleans. He's to meet emergency personnel who've been laboring since the storm hit last week to restore power and tend thousands of evacuees from flooded lands.

Romney issued a statement marking Labor Day as "a chance to celebrate the strong American work ethic." But he added: "For far too many Americans, today is another day of worrying when their next paycheck will come."
