A new Public Policy Polling poll shows Sen. Kay Hagan, D-N.C., is struggling with growing unpopularity as her disapproval ratings are up 10 points since September.
Hagan will not be attending an event with President Obama on Wednesday, as the president plans to return to N.C. State University to promote his economic agenda.
Hagan, who is seeking re-election this year, now has a disapproval rating of 49 percent.
Obama's push for an economic agenda in the state might be overshadowed by the unpopularity of Obamacare.
According to the poll, 61 percent of voters say that the Obamacare rollout has been unsuccessful.
Hagan is now virtually tied with her Republican challengers, according to the poll, which has a margin of error of plus or minus 3.7 percentage points.
