Where does the party go next? Matsui, Vang race for Congress reflects broader Democratic Party debate

For the first time in more than two decades, Sacramento Congresswoman Doris Matsui heads into a general election after finishing behind her opponent in the primary. 

Now she'll face fellow Democrat Mai Vang in November’s runoff for California’s 7th Congressional District. Matsui, who will be 82 in September, faces a challenger who’s running for Congress for the first time, is far to her left politically and about half her age.

The Matsui name in Sacramento is synonymous with Democratic politics: Doris Matsui has served in Congress since March 2005. That’s when she won a special election to take over the seat that had been held by her husband, Robert Matsui, who had died two months earlier. Robert Matsui had represented California’s Capital region in Congress since 1979. 

But despite, or perhaps because of her longevity in office, political observers say Matsui could be pushed aside this fall if the wave of anti-establishment sentiment within the Democratic party continues to crash down on longtime incumbents.

At Vang's election night party in June, the celebration reflected something few political observers expected just months earlier. After trailing in early vote counts, the Sacramento City Councilmember finished first in the primary. Vang finished first with 30.8% of the vote, ahead of Matsui's 29.1% — a difference of 3,510 votes. 

Across town the mood sounded different. Matsui was measured but confident. The incumbent went into election night with endorsements from local leaders, like Sacramento Mayor Kevin McCarty and Governor Gavin Newsom. 

“I feel good about where we are. I felt the energy on the ground and it was really wonderful,” Matsui said on election night. 

At that point, thousands of ballots still remained uncounted. The final tally would eventually show Vang finishing ahead. The contest has become about much more than two Democrats. It's also become a test of experience versus change.

Nathan Gonzales is the editor of Inside Elections, which analyzes congressional races across the country. 

“Right now, based on what we're seeing in the district and nationwide, I think Congresswoman Matsui is at significant risk of losing re-election,” Gonzales said in a July interview.

Gonzales said Sacramento’s race reflects a broader national trend. In recent weeks, younger progressive candidates backed by Democratic Socialists of America chapters have defeated longtime Democratic incumbents in New York and Colorado.

Vang has campaigned as a progressive Democrat advocating for policies like Medicare for All. She’s also taken a more critical stance on U.S. support for Israel.

Matsui, by contrast, has emphasized her experience and influence in Congress, including the relationships she's built in Washington.

But Gonzales said those qualities could be a liability this fall.

"Democratic incumbents, particularly aging Democratic incumbents, are facing pressure from a Democratic base who wants younger, fresher voices and more of a fighting message and maybe even a more liberal or progressive ideology,” Gonzales said. 

At their lone debate during the primary, Vang criticized Matsui for the way she raises money.

"There are clear contrasts in terms of who we are, our values, and also where we get money from. I don't take any corporate PAC money. Doris Matsui does,” Vang said. 

Matsui on election night focused on her own accomplishments such as securing funding for the Folsom dam and other regional projects.

"I really don't know what quite her policy issues are, but I will tell you this: I have fought against Donald Trump. I fought against ICE. I really believe that healthcare is fundamental, and we need universal healthcare. We need to make sure that we move everything forward,” Matsui said.

With Republicans off the ballot in November, the two Democrats now compete for the roughly 44,000 voters who backed GOP-candidate Zachariah Wooden.

Sacramento State political scientist Kim Nalder said Republican voters may have a tough time deciding what they do for this race. 

"This presents kind of a dilemma for them,” Nalder said. “Do they go for the more moderate candidate, which would be Matsui, or do they just sit it out?"

The district, which was redrawn after the last round of redistricting, stretches from central Sacramento through Elk Grove and Galt.

Wooden, a Sacramento State student who finished third in the primary, said many Republicans will feel they have nobody who represents them.

"I am not going to be voting for either candidate in this race. It's possible that many Republicans also end up doing so,” said Wooden. “When the general comes around you're going to want as many votes as possible. Whether that's Matsui or Vang attempting to appeal to Republican voters, I wouldn't be surprised."

Mindy Romero directs the Center for Inclusive Democracy. She said longtime incumbents rarely trail challengers.

"There's something happening with voters wanting something different,” Romero said. “But still, it's an uphill battle for anybody to challenge a long-time incumbent."

Matsui said her second place finish in the primary shows voters wanted more from her.

“I think that, I looked at the primary vote and, I think all my colleagues say the same thing,” Matsui said. “Voters are just upset and frustrated about what's going on, particularly in Washington, and I don't blame them because I feel the same way, too.”

Both Matsui and Vang will compete for voters who backed someone else just weeks ago.

Vang said she will try to prove the coalition that carried her through the primary can grow large enough to win in November. 

“What you're seeing is voters across this country showing they're ready for a new generation of leadership. Progressive candidates are viable,” Vang added.

Gonzales said Vang’s surprising win in June follows a wave of upset victories by candidates backed by the Democratic Socialists of America — a group that supported Vang.

Vang acknowledged receiving the endorsement of Sacramento's Democratic Socialists of America Sacramento chapter but describes herself as a progressive Democrat focused on working families.

Gonzales said those upset victories came at the expense of establishment Democrats like Matsui.

"Her share of the primary vote has steadily declined over the years but bigger picture, looking nationally, she is the type of incumbent we have seen lose,” Gonzales said. 

Whether Sacramento voters ultimately choose continuity or change won't be decided until November.
