Tricia Cotham, a Democrat who supported abortion rights, was encouraged to run for a state House seat by powerful Republicans. After she was elected, she joined them and delivered a G.O.P. supermajority.
She was recruited as a likely party-switcher by the GOP, falsely campaigned on a democratic platform, and after the election indeed switched parties and is now doing the opposite of what she was elected to do.
She really should be recalled, not sure if that's a thing in North Carolina state elections.
