The new Fox News poll of the Colorado Senate race gives Republican nominee Ken Buck a narrow lead over appointed Democratic Sen. Michael Bennet.
The numbers: Buck 47%, Bennet 43%. The survey of likely voters has a ±3% margin of error. There is no previous Fox News poll of this race. However, this poll was conducted through a Rasmussen offshoot, Pulse Opinion Research, which performs made-to-order robopolls. In the previous Rasmussen poll from two and a half weeks ago, Buck led by a similar four-point margin of 49%-45%, but with fewer undecideds.
The TPM Poll Average gives Buck a lead of 47.2%-43.4%.
