BEN FELLERWEST CHESTER, Ohio (AP) â¿¿ Down to a fierce finish, President Barack Obama accused Mitt Romney of scaring voters with lies on Friday, while the Republican challenger warned grimly of political paralysis and another recession if Obama reclaims the White House. Heading into the final weekend, the race's last big report on the economy showed hiring picking up but millions still out of work. "Four more days!" Romney supporters bellowed at a rally in Wisconsin. "Four more years!" Obama backers shouted as the president campaigned in Ohio. With Ohio at the center of it all, the candidates sharpened their closing lines, both clutching to the mainstream middle while lashing out at one another. Virtually all of the nine homestretch battleground states were getting personal attention from the contenders or top members of their teams, and Romney was pressing hard to add Pennsylvania to the last-minute mix. Romney drew the largest crowd of his years-long quest for the presidency at an Ohio rally attended by 18,000 people on a cold Friday night. "We're almost home," a confident Romney, surrounded by family and more than a dozen Republican officials, told a sea of supporters. "One final push will get us there." Urgency could be felt all across the campaign, from the big and boisterous crowds to the running count that roughly 24 million people already have voted. Outside the White House, workers were setting the foundation for the inaugural viewing stand for Jan. 20. Lawyers from both camps girded for a fight should the election end up too close to call. Obama, for the first time, personally assailed Romney over ads suggesting that automakers General Motors and Chrysler are adding jobs in China at the expense of auto-industry dependent Ohio. Both companies have called the ads untrue. The matter is sensitive in Ohio, perhaps the linchpin state of the election.
