Donald Trump has been overtaken in a key polling average for the first time in 4 months
The site averaged the results of four recent polls, including Wednesday's Quinnipiac survey that showed the two Republican outsiders in a virtual tie for first place.
According to the average of the four polls, Carson gets 25.3% of the vote to Trump's 24.3%.
It's the first time since July 19, when Trump was running second to former Florida Gov. Jeb Bush (R) in the average, that he has not led.
