New Hampshire poll: Hillary's lead over Bernie Sanders down to just six points

The WMUR Granite State Poll taken July 22-30 shows frontrunner Clinton with a 6 percentage point lead over the challenger from Vermont. The poll has a margin of error of plus or minus 5.9 percent, prompting the pollster to call the race a statistical tie.

The poll shows Clinton leading Sanders 42 percent to 36 percent, with 5 percent supporting Vice President Joe Biden, who has been the subject of speculation in recent days about the possibility of becoming a candidate. Former Maryland Gov. Martin O’Malley and former U.S. Sen. Jim Webb of Virginia each receive 1 percent, with 3 percent favoring some other candidate and 12 percent undecided.

A WMUR Granite State Poll released in May showed Clinton leading U.S. Sen. Elizabeth Warren of Massachusetts 51 percent to 20 percent, with Sanders at 13 percent. Warren, after repeatedly insisting she will not run for president, was not included in a June poll, and Sanders picked up much of her support.
