(CNN) - Color North Carolina light red.

Four years ago then Sen. Barack Obama became the first Democrat since 1976 to carry North Carolina in a presidential election. And this summer the Democrats held their nominating convention in Charlotte.
While the Obama campaign continues to run ads in North Carolina, spending just over $1.2 million to run spots over the past week, according to Campaign Media Analysis Group, which tracks ad spending for CNN, the president hasn't made a campaign stop in the state since his nomination at the Democratic convention in early September.
Last week, in a clear sign it's confident about turning the state from blue to red, Republican nominee Mitt Romney's campaign moved its North Carolina spokesman out of the state and planned to shift more staffers to other states.
This week the Obama campaign denied that they were giving up on North Carolina, saying they have a "credible pathway to 50%" in the state. But some campaign officials privately acknowledge that the state, which Obama can afford to lose, is moving out of reach.
With the shift of North Carolina, CNN now estimates that Romney is leading in states with 206 electoral votes. The shift does not affect CNN's estimate that Obama is leading in states with 237 electoral votes. Two-hundred and seventy electoral votes are needed to win the White House.
CNN is also shifting Indiana and Missouri, two states that are currently "lean Romney," to "safe Romney." Obama carried Indiana four years ago, becoming the first Democrat since 1964 to win the state in a presidential election. And he narrowly lost Missouri to Sen. John McCain, the 2008 GOP nominee.
But this cycle, the Obama campaign has not seriously contested either state.
The moving of Indiana and Missouri does not affect the electoral count.
