Two political newcomers are running for the open Senate District 10 seat in the heart of Great Falls

If you live in central Great Falls, your state senator's seat is open this fall. Incumbent Jeremy Trebas chose not to seek re-election, KRTV reports, and two newcomers want the job. The district sits south of the Missouri River and runs from 10th Avenue South over to 38th Street.

Democrat Margaret Mitchell is a fourth-generation Great Falls resident and a software engineer who was a vice president at American Express. She says she wants tax credits to get more starter homes and affordable apartments built. Republican Jessica Dyrdahl is an Army National Guard veteran and former Chouteau County dispatcher. She's a single mother of two, and parental rights and child safety are her top issues. "Groceries are really expensive. Gas is really expensive," she said.

Montana Free Press says in its roundup of Cascade County races that this one may be the closest race on the ballot. "It's definitely a seat that is competitive," said Eric Hinebauch, chair of the Cascade County Republican Central Committee. Two House districts sit inside the Senate district, each with one incumbent from either party. Trebas told MTFP those districts have historically seen the most swing between parties.

Ballots were mailed Fri., Oct. 9, and Election Day is Tue., Nov. 3. The MTFP roundup also covers Senate District 11, House District 20 and the Cascade County commissioner race.

A Great Falls rancher says the new federal and state diesel moves won't do much for his bottom line

If you drive a commercial vehicle for farm, ranch or timber work, there's a new rule you should know about. Lt. Gov. Kristen Juras issued an executive order Friday that lets commercial vehicles engaged "directly in agricultural or timber industry operations" use on public roads until Nov. 23, Montana Free Press reports. It follows an executive order from President Donald Trump suspending the federal ban on driving with dyed fuel.

Tim Brunner, a rancher near Great Falls and president of the Montana Cattlemen's Association, doesn't expect much relief. The dye stays in a tank after the fuel is gone, he said, so a test after the exemption ends could show a false positive. "In another year, get your tank dipped. It shows red. There's $1,000 right there," Brunner said. Over the weekend he hired semi trucks to haul his herd home from 125 miles north, and the bill he got Monday included an 8.5% diesel surcharge.

Walt Schweitzer, president of the Montana Farmers Union, said the policy comes "too late" for most farmers hauling grain. He also said it may be "confusing and difficult to manage" for interstate truckers.

Then there's the Russian diesel. MTFP reports Trump announced a plan to import about 800,000 tons before the end of November. The Great Falls Tribune reports Trump's Oct. 9 post promised 300,000 tons immediately and 1 million tons in November, and that Treasury is lifting Russian oil sanctions through April 7, 2027. Rory Johnston, an oil market researcher, noted the November amount equals 125,000 barrels per day. Sen. Thom Tillis, a North Carolina Republican, said on "Meet the Press" that Trump "may be" breaking the law. The Tribune says diesel averages above $6 a gallon nationally.

Until then, commercial vehicles working directly in agriculture or timber can run on public roads. Brunner warns that leftover dye in a tank can still test red afterward.

Politics

Montana Democratic Party chair resigns and endorses independent Seth Bodnar for Senate

If you've been following the U.S. Senate race on your ballot, it just got messier. Shannon O'Brien resigned as chair of the Montana Democratic Party, effective immediately, and endorsed independent Seth Bodnar, Montana Free Press reports, citing a statement published by MS NOW. "I ran for state party chair to unify Democrats," O'Brien wrote. "But there are things more important than labels or party politics."

She wrote that Democratic nominee Alani Bankhead "does not have the momentum, resources or will to win this race." KECI adds that O'Brien raised questions about Bankhead's commitment to protecting a woman's right to choose. KECI also reports she pointed to U.S. Sen. Steve Daines' last-minute decision to pull out of the race and endorse Republican Kurt Alme.

Bankhead pushed back in a statement sent to both outlets: "Shannon didn't switch sides today. She's been working against the Democratic nominee since the summer." She said O'Brien got a legal opinion on whether the party could refuse to replace Bankhead if she quit, without a vote of her own board.

Vice Chair Bruce Knutson is now party chair. "We have doors to knock, voters to reach and seats to win," he said. Bodnar, Bankhead, Alme and Libertarian Kyle Austin debated Sunday in Bozeman. A Montana Free Press-Eagleton poll last month had Alme eight percentage points ahead of Bodnar, with Bankhead 14 points behind Bodnar.
