Two days before polls close in Montana’s special congressional election, the leaders of the Democratic Congressional Campaign Committee offered some ultracautious optimism — and reemphasized their hopes for winning a June 20 runoff in Georgia.

“Rob Quist continues to run a strong, Montana-focused campaign,” DCCC Chairman Ben Ray Luján said at a morning briefing for reporters, referring to the party’s populist candidate. “The Republican health-care repeal bill continues to be a disaster for all Republicans, across the map.”

Moments later, Luján announced that the DCCC was pouring $2 million more into Georgia’s 6th Congressional District, where Democrat Jon Ossoff is narrowly leading the most expensive House race in history. That investment, partially earmarked for African American voter turnout, will put the DCCC’s spending in Georgia 10 times higher than its spending in Montana.

Republicans, who are more optimistic about holding the Montana seat, spent more and spent it earlier. The closing spots from the National Republican Congressional Committee and the Congressional Leadership Fund, the main Republican super PAC, both hit Quist on a series of tax problems and late payments to contractors, a theme Republicans have worked since the country singer-turned-candidate won the nomination.

“It’s a tough road in Montana,” Lujan said.

The implication: It was not as tough in suburban Atlanta, where a poll this week showed Ossoff holding a comfortable lead for the first time since the race began. SurveyUSA, a pollster that relies on automated calls, found Ossoff up by 7 points ahead of the June 20 runoff, with a 31-point lead among self-identified independents. Forty-eight percent of voters told the pollster that Ossoff’s current residence outside the district was either a “major” or “minor” issue, but a proportion of those voters were backing him anyway, blunting the impact of an attack Republicans have used for months.

On Tuesday night, Democrats got more good news from the sort of suburbs where, increasingly, they hope they can build a House majority. In New Hampshire, the party won a special state legislative race in Wolfeboro, a traditionally Republican town. Donald Trump had carried the district by 7 points, a decline from Mitt Romney’s 2012 performance; Democrat Edith DesMarais became the first member of the party to win a Wolfeboro seat.

In New York, Democrats scored an upset in an equally Republican area, the 9th state assembly district that covers a stretch of Long Island coastline. In 2016, Trump — a New York native who outperformed recent Republican presidential nominees — won the district by 23 points. But anti-Common Core activist and 2016 Bernie Sanders delegate Christine Pellegrino won in a rout, giving Sanders supporter a data point to argue for running progressives in risky districts.
