“I’m tired of it,” Scolamiero said. “And I want someone who’s outside of the system, who’s not going to game the system for their own ends.”

Carson had also benefited from that sentiment. But the new WBUR survey, conducted by the MassINC Polling Group, shows Carson’s appeal may be waning.

Carson was in a near tie with Trump in September, but he’s 10 points behind now, with 13 percent support.

MassINC Pollster Steve Koczela says voters gave Carson an early honeymoon, but the attraction is fading.

“The counter example to that is Marco Rubio,” Koczela noted, “where the better voters get to know him the more they like him.”
