Stubbornly close and deeply divisive, the presidential race throttles into its last 100 days as an enormous clash over economic vision, with the outcome likely to come down to fall debates, final unemployment numbers and fierce efforts to mobilize voters. It may seem like an election for the whole nation, but only about eight states will decide who wins the White House.

Polling shows the contest between President Barack Obama and Republican Mitt Romney remains remarkably static across the country and in those pivotal states even as both men and their allies pour money into largely negative television advertising to sway opinions.
