(CNN) - New polls released Thursday indicate President Barack Obama and Mitt Romney are essentially tied in three battleground states for the presidential race.
The president holds a slight advantage over his Republican rival in Michigan and North Carolina while polling dead-even with Romney in New Hampshire, according to the new NBC-Marist surveys. All three states' results fall within the sampling error for their respective polls.

In Romney's native state of Michigan, he's slightly edged out by Obama, 43% to the president's 47%. While CNN's Electoral Map rates Michigan as leaning towards Obama, Romney included the state in his recent bus tour, suggesting he sees it in play for the fall.
In North Carolina, Obama holds a two-point margin over Romney, 46% to 44%. CNN also rates the state as leaning towards Romney, though Obama narrowly carried it in 2008.
In New Hampshire, which CNN rates as a toss-up, Obama and Romney both stand at 45% support among voters, according to the new poll.
Romney, who once served as governor of neighboring Massachusetts, campaigned heavily in the Granite State and won its presidential primary by a landslide earlier this year. Obama, however, won New Hampshire in 2008.
The NBC-Marist polls were conducted by telephone with 1,078 registered voters in Michigan with a sampling error of plus or minus 3 percentage points, 1,029 registered voters in New Hampshire with a sampling error of plus or minus 3.1 percentage points, and 1,019 registered voters in North Carolina with a sampling error of plus or minus 3.1 percentage points.
