(CNN) - A new poll in New Hampshire shows the number of likely voters there unsure of who will receive their presidential vote in November has spiked in recent weeks while the race remains locked in a statistical tie.
The percentage of likely voters who were undecided or favoring a non-major candidate there had remained steady between 6% and 9% since February 2011, according to the WMUR Granite State Poll, but that number shot up to 15% in the most recent sampling.

This survey includes voters contacted between September 4 and 10, so it includes voters contacted both during and after the Democratic National Convention, which was taking place that week. All voters were contacted after the Republican National Convention, which was held the preceding week.
President Barack Obama and Republican presidential nominee Mitt Romney are statistically tied, with 45% favoring Obama and 40% supporting Romney. The poll's sampling error is plus or minus four percentage points.
The August iteration of this survey also found a tied race - 49% for Obama and 45% for Romney - with each candidate apparently having contributed nearly evenly to the growth in undetermined voters since then.
New Hampshire has four electoral votes and is one of the nine states considered a toss up on the CNN Electoral Map.
Independent likely voters in the Granite State were most likely to be undecided, with one in four fitting that category.
The survey showed Obama's favorability rating went up nine points to 52% since the August poll, while Romney's dropped three points to 45%. It also found Vice President Joe Biden and Republican vice presidential candidate Paul Ryan both had a favorability rating of 39%.
A separate poll of voters in Michigan also released Thursday found 16% of likely voters there were undecided. Michigan is rated as leaning in Obama's favor on the CNN Electoral Map, and the EPIC/MRA poll found he held a 10 point lead over Romney there.
Several other state polls released Thursday showed a statistically tied race in Colorado, Florida, Ohio, and Virginia. The NBC News/Wall Street Journal/Marist poll found Obama slightly ahead in Ohio.
The WMUR Granite State Poll was conducted by the University of New Hampshire and included 592 likely voters reached by telephone between September 4 and 10. It has a sampling error of plus or minus four points, while a larger sample of 635 registered voters had a sampling error of plus or minus 3.9 points.
Every poll is in favor of the president over Romney but it is reported as the two are statistically tied. Obama has more numbers in his favor and building and with Mitt the twit nervous out bursts, he may just coast to the finish line.
Mitt resembles a sweaty gorilla. Ugh.
Just look at the unemployment numbers, it went up again today. Romney is the correct choice. Our country cannot continue to have families unemployed and Obama giving us excuses and still blaming Bush and then blaming Congress, Republicans and whatever else that can be blamed. It is just ridiculous to continue to wait on Obama, we need to hire someone new.
Lets hope the American people will come out in big numbers to support President Obama. I can't believe the majority would vote for Mitt the Twit or Lying Ryan. Do some homework folks and see for yourselves that they only care about the 1% and lining their own pockets by cutting taxes on the rich and cutting Social Security and Medicare. I am a registered Republican who will never vote for the GOP again.
Oh Mitt may take another Blue State away. With the Obama economy putting more people in poverty than ever it's easy to see why.
Believe me....NH isn't going to vote for Obama!
Libya plot is ISRAEL drama.
He is disgusting. They will give him intel briefings starting next week. So? bachmann has been on intelligence committee for 4 years and she's still stupid. He can't get enough intelligence in the next 24 days to make me change my mind. He's all for himself and his wealthy buddies.
24 days til early voting in my state.
Obama/Biden 2012-2016 for a calm, intelligent, steady hand going forward.
.....so 45% to 40% is a tie?
CNN, please check the numbers. 5-point leads outside the margins of error are not statistical ties.
Mistake 1 Try to defend Ryan with 716 billion lies Bill Clinton hammer it down
Mistake 2 Foreign tour didn’t go well with cameras and microphones
Mistake 3 convention speeches fill with “I”s
Mistake 4 couldn’t keep up the speed with media
Mistake 5 Still same staffs
Romney go home, people are smarter than you think they are. You have sold nothing to them. What a shame that you put yourself forward to win without any idea or how you will do things differently.
However mr king tries to play these numbers its clear romney is not doing at all well.
So close to the election many are firmly decided and les and less open to swithcing sides and the uncommited in most states are small... overall bad news for Romney.
