North Dakota Sen. Heidi Heitkamp is one of the more vulnerable Democrats up for re-election this year, but Republicans are the ones worrying about her race, Politico reports.

Battle lines: President Trump recruited her challenger, Rep. Kevin Cramer, but he invited Heitkamp to a bill signing last week and hasn't attacked her (yet.) Just last night at a rally in Tennessee he said, referring to Heitkamp and other red-state Democratic senators, "Democrats running for office, many of them, are saying great things about me — in fact, I think they're Republicans."
