Rep. Bruce BraleyBruce BraleyTrump: Ernst wanted 'more seasoning' before entertaining VP offer Criminal sentencing bill tests McConnell-Grassley relationship Trump's VP list shrinks MORE (D-Iowa) has a narrow lead over Iowa state Sen. Joni Ernst (R), according to a new poll from Quinnipiac University.
That's a bump for Ernst since the last time Quinnipiac polled in March, when she was just starting to gain traction in the primary and before his "farmer from Iowa" comments surfaced.
Two other polls conducted immediately after the primary, one by a nonpartisan pollster and one by a Republican, found her with narrow leads. But those might have been picking up on post-primary enthusiasm for Ernst.
The live-caller poll of 1,277 registered voters was conducted on landlines and cellphones from June 12-16 and has a margin of error of plus or minus 2.7 percentage points.
