Ben Carson Leads In New National Poll

One day ahead of the next GOP debate, Ben Carson has taken the lead in a national poll for the first time. Business Insider reports:

While volatility is expected in primary polls, this latest development is notable because of how completely Trump has dominated such surveys since the summer, when he rocketed to the top. But Carson gained the lead in two Iowa polls last week, while Trump remained ahead in the national ones. Trump responded to the Iowa results by aggressively taunting Carson in his stump speeches and media interviews. Among other things, Trump called Carson “super-low energy,” said he was controlled by his super PAC, blasted him as “extremely weak” on illegal immigration, and even appeared to question his Seventh-day Adventist faith. “He’ll hit back, everybody hits back,” Trump predicted Monday of Carson, who has yet to return fire. “In life, everybody hits back.”
