Democrats have singled out Mr. West as one of their key freshmen to defeat. “He is the king of rhetoric,” said Mitch Ceasar, the chairman of the Democratic Party in Broward County. “And that is what separated him in 2010. But what swept him in then may be the gust of wind that sends him out.”…

Mr. West’s place in the Democratic crosshairs stems, he said, from the fact “that I scare the liberal establishment.”

“You’re looking at a black man who was brought up in the inner cities, career military, a conservative, married going on 22 two years, two beautiful daughters, and for whatever reason that really does scare them,” he said. “My theory is that for whatever reason I could cause others like me to reject these liberal social-welfare policies.”
