NY Times: “Three months after Ms. Cotham took office in January, she delivered a mortal shock to Democrats and to abortion rights supporters: She switched parties, and then cast a decisive vote on May 3 to override a veto by the state’s Democratic governor and enact a 12-week limit on most abortions — North Carolina’s most restrictive abortion policy in 50 years.
Overnight, Ms. Cotham became a heroine to Republicans and anti-abortion advocates across the country, even as Democrats vilified her as a traitor whose unexpected party flip had changed health care policy in a politically purple state of more than 10 million people.
More perplexing to many Democrats was why she did it. Ms. Cotham came from a family with strong ties to the Democratic Party, campaigned as a progressive on social issues and had even co-sponsored a bill to codify a version of Roe v. Wade into North Carolina law.
Interviews with former and current political allies depict her as someone who had grown alienated from Democratic Party officials and ideals. Republican leaders cultivated her before she ran and, seeing her growing estrangement, seized a chance to coax her across party lines.
Before the switch, Ms. Cotham chafed at what she perceived as a lack of support from other Democrats. Once she was elected, Mr. Moore said, he made it clear that she would be welcomed by Republicans.”
