FILE - In this Sept. 18, 2012, file photo, Republican vice presidential candidate Rep. Paul Ryan, R-Wis., takes questions during a campaign stop in Dover, N.H. Political mailers are stuffed in their front doors and the phone rings nonstop. Under a fall canopy of crimson and golden leaves, the battle for independent voters is being waged hour by hour in battleground New Hampshire. The state offers only four electoral votes in next week's presidential election, but President Barack Obama and challenger Mitt Romney are vying fiercely here for the remaining independent voters, who are decidedly ambivalent about either candidate.
