Blevinsâ announcement comes a day after Christiansburg businesswoman Marie March, who lives in Floyd County, said she is also seeking the GOP nomination. âI was saddened and just surprised that Delegate Rush will not seek re-election and, shortly after that news broke, I was just encouraged by many folks reaching out to me, with the concerns that we want to move the New River Valley forward,â Blevins said.
