Here's some good news regarding the Grassley/Judge race.
A new poll of Iowa shows Sen. Chuck Grassley (R-Iowa) with
just a 1-point lead over his Democratic challenger and Hillary Clinton with a double-digit advantage on Donald Trump in the presidential race.
...
Senator Grassley is something of an institution here in Iowa, but Democrats are hoping to use his refusal to hold a Senate hearing on President Obamas Supreme Court nominee against him," he said.
"I think they are also hoping for a negative down-ballot effect created by Trump as the presidential nominee. Senator Grassley will not be easy to unseat, however."
While the poll shows the results of the race are close, 70 percent of those surveyed said they expect Grassley to win.
"Still, in this volatile year, Senator Grassley appears to be facing a tougher challenge than most people would have predicted earlier this year," Budzisz added.

Here's the poll:

The Loras College Poll surveyed 600 likely Iowa 2016 presidential election voters by live operator. The survey was conducted June 24-28, 2016. Margin of error for full sample results is +/- 4%. Margins of error for subgroups are higher. All results calculated at a 95% confidence interval. The partisan composition of the sample was 35 percent Republicans, 33 percent Democrats, and the remaining 32 percent No Party/Other. Poll results for the complete sample have a margin of error of +/- 4%. Percentages may not add to 100% due to rounding.
I'm cautiously optimistic.
