The Quinnipiac poll released Tuesday found Christie would beat out Clinton 45 percent to 40 percent when Iowa voters are asked who they'd favor for president.
That is a 5-point improvement for Christie since the firm last tested the question in July. It also follows a GOP poll earlier this month that found similar results.

Clinton narrowly tops Paul with 45 percent compared to his 44 percent.
Fifty-three percent say Clinton would make a good president; 46 percent say the same about Christie and 38 percent feel the same about Paul.
Rep. Paul Ryan (R-Wis.), the former GOP vice presidential candidate who hashed out a budget agreement last week, was not included in the poll.
However, a Des Moines Register poll over the weekend showed him with the highest favorability rating among Republicans.
The Quinnipiac poll surveyed 1,617 people and has a 2.4 percent margin of error.
