The worst-case scenario came to pass today: after months of below-average snowfall, a huge winter storm hit most of the state hours before the 2018 caucuses. According to anecdotal reports and a statement from the Iowa Democratic Party, turnout on the Democratic side far surpassed the level seen in 2010 or 2014. John Deeth estimated that Johnson County Democrats “at least doubled our previous governor year caucus turnout record.” But poor road conditions surely kept thousands of politically-engaged people home tonight. I had hoped good weather would reveal how many activists were “fired up and ready to go.” UPDATE: Added below a “soft report” from the state party: with 80 percent of precincts reporting, attendance was 8,599. “While we are still getting results in, we expect turnout will exceed 9,000, which far eclipses the 5,000 attendees in 2010 and the 6500 attendees in 2014.”

Former presidential candidate Bernie Sanders gave Pete D’Alessandro, one of seven Democrats running for Congress in Iowa’s third district, his “strongest” endorsement on January 29, Jason Noble reported for the Des Moines Register.

For the first time in Iowa history, multiple gubernatorial candidates are airing television commercials four and a half months before the primary. Fred Hubbell’s campaign launched its fourth statewide tv ad last week, while the first spot for Democratic rival Nate Boulton hits the screens today in the Des Moines and Cedar Rapids markets. UPDATE: Cathy Glasson has placed a television ad buy too. Iowa Starting Line reported today that committees affiliated with the Service Employees International Union have donated $1,819,931 to Glasson’s campaign already.

The new Hubbell ad references the themes of his campaign’s first three spots: support for Planned Parenthood, mental health funding, and better economic development practices. (Bleeding Heartland published those videos here, here, and here.) Boulton’s commercial highlights his role leading the opposition to Republican efforts to strip away collective bargaining rights during last year’s legislative session. Scroll down for details on both ads.

Hubbell has been on the air for months, having raised well over $1 million since last summer. Boulton’s campaign war chest is likely to be substantially smaller–we’ll know for sure when all the 2017 finance reports are published later this week. While candidates normally conserve their cash to use on television and radio spots closer to the primary, Boulton has good reason to spend some money now.

The Iowa Democratic precinct caucuses are coming up on Monday, February 5. Caucus-goers will elect county convention delegates, who in turn will select district and state delegates at county conventions on March 24. With seven Democrats running for governor, state convention delegates may end up selecting the nominee on June 16, if no candidate receives at least 35 percent of the vote in the June 5 primary.
