A new poll reveals that Sen. Chuck Grassley (R-IA) is in the race of his Senate career against Democratic opponent Patty Judge.

Judge – the former lieutenant governor – is within striking distance of the seven-term senator, polling at 45 percent among likely voters compared to Grassley’s 46 percent.

The Loras College poll released Thursday was its first since Trump and Clinton won their respective primaries. It suggested Grassley may be more vulnerable in his re-election after refusing to hold hearings on President Barack Obama’s Supreme Court nominee Merrick Garland. Christopher Budzisz, the director of the poll, also added that Republican nominee Donald Trump–who was trailing Hillary Clinton by double digits statewide in the poll, may also be a drag on Grassley.

The poll revealed, however, that many people are still skeptical Grassley can be beat. Even with Judge within a single point of Grassley, 70 percent said they thought Grassley would keep his seat in November.

The survey of 600 likely voters was conducted between June 24-28. The margin of error was 4 percentage points.
