Automakers to Obama and Romney: stay away

General Motors Co and Chrysler Group LLC, US automakers that received billions of dollars in government help to stay afloat during the recent recession, said they will not allow presidential candidates to make stops at their plants.
President Barack Obama often touts the financial health of both GM and Chrysler and has appeared at auto plants of both companies frequently in the past several years.
While the federal government still owns 26 percent of GM's shares, Obama cannot go to a GM plant until after the Nov. 6 election, GM said.
