Iowa Senate President Pam Jochum endorsed Hillary Clinton for president today in a guest column for the Des Moines Register. This afternoon, she will elaborate on her reasons at a Women for Hillary event in Dubuque.

Jochum joins the list of prominent Iowa supporters of Barack Obama before the 2008 caucuses who are now backing Clinton. An Iowa House Democrat at that time, Jochum headed Obama’s leadership team in Dubuque County. Obama easily won a plurality of delegates in Dubuque and carried all of the neighboring counties too.

More important, Jochum is a hero to many on what you might call “the Democratic wing of the Iowa Democratic Party.” I’m thinking of the 26 percent who voted for Ed Fallon in the 2006 gubernatorial primary, as well as people who have long advocated for campaign finance reform at the state level. Although I think highly of Senate Majority Leader Mike Gronstal, he’s not the progressive champion Jochum is–not by a long shot. She has helped fight some very tough fights, where powerful interest groups were lined up on the other side. I can’t think of an Iowa state legislator in my lifetime who has reached such a senior leadership position while being as consistently progressive as Jochum.

My impression is that many on the “Democratic wing” of the party have already committed to caucus for Bernie Sanders. Others feel conflicted as I do, drawn to Sanders for his passion and his uncompromising policy agenda, while recognizing Clinton’s strengths as a candidate and what it would mean for this country to elect a woman president. That Jochum is on board with Clinton could carry a lot of weight with undecided Democrats like me.

Before today, eight Democratic state senators and nine state representatives had already endorsed Clinton for the 2016 caucuses. I’ve enclosed the full list after the jump, along with excerpts from Jochum’s Des Moines Register op-ed.
