GOP Rep. Rick Berg has a slight, 2 point edge on Democratic opponent Heidi Heitkamp in a new poll of the tight North Dakota Senate race -- a big difference from a Forum Communications Co. poll conducted in mid-October and showing Berg with a 10-point lead.
The Mason-Dixon poll, conducted for KVLY-TV/KFYR-TV, shows Berg leading Heitkamp 47 percent to 45 percent. Their previous poll, conducted in early October, had the two tied at 47 percent.
A gender gap exists on both sides: Berg wins among male voters, 57 percent to 38 percent, while Heitkamp wins among female voters, 52 percent to 37 percent. Heitkamp leads 96 percent to 2 percent among Democrats while Berg leads 88 percent to 7 percent among Republicans. Heitkamp has a 10 point lead, 48 percent to 38 percent, among independents.
Mitt Romney continues to hold a hefty lead over President Obama in the state's presidential race: 54 percent to 40 percent.
The poll was conducted October 26-28 and surveyed 625 likely voters. It has a margin of error of plus-or-minus 3.9 percent.
