(CNN) – New polls taken before the final presidential debate indicate that the race for the White House is all knotted up between President Barack Obama and Republican nominee Mitt Romney in two key states.
American Research Group released the surveys on Tuesday in battleground states showing Obama with a slight edge in Nevada, 49% to Romney's 47%, and Romney with the advantage in New Hampshire, 49% to Obama's 47%. But the results are well within the poll's sampling error making it a statistical tie.

The Nevada survey shows Romney gaining ground among men, 49% to the president's 48%. Obama was ahead of Romney among the group in American Research Group's September survey – 49% to 46%.
The poll also shows Romney with the edge among likely voters over the age of 50 in Nevada, 48% to Obama's 47%, compared to last month's poll where Obama led among the group, 51% to Romney's 42%.
Among those saying they have voted early or by absentee ballot, Obama does hold a lead of 57% compared to Romney at 43%.
In New Hampshire, Romney has the advantage over Obama, 49% to 47%, but the president's support has increased slightly among independent or undeclared voters and is now tied with Romney in the group at 48% each. In a survey conducted from October 9-11, Romney was ahead of Obama by a three point margin among undeclared voters, 48% to Obama's 45%. These results are also within the sampling error.
Another survey from the University of New Hampshire Survey Center of likely New Hampshire voters released Monday showed Obama with an eight point lead in the state, with 49% support compared to Romney's 41%. The UNH poll was also taken before the final presidential debate.
Both of the American Research Group's surveys released Tuesday were conducted from October 19-22 from interviews with 600 likely voters in Nevada and New Hampshire, each respectively. The surveys' sampling errors are plus or minus four percentage points.
Nevada has six electoral votes and New Hampshire has four. CNN rates both states as "toss ups" in November's election.
Romney campaigns in Nevada with vice presidential running mate Paul Ryan Tuesday, later attending a rally in Colorado.
Meanwhile, Obama campaigns in Florida and then joins Vice President Joe Biden in Ohio.
