The lines are drawn in Napa County’s District 5. Or at least they were on June 3, when voters weighed in on who will be the next Napa County supervisor representing the area.

Former American Canyon Fire Chief Keith Caldwell dominated in that city, while two other candidates — former Napa County Sheriff Gary Simpson and current Napa County Planning Commissioner Rich Jager — gained strong support in Napa and unincorporated parts of the county.

Caldwell and Simpson were the top two vote-getters overall, at 34 and 30 percent, respectively. They will face each other in a November runoff.

Jager finished third with 25 percent of the vote, and American Canyon City Councilwoman Cindy Coffey finished fourth with 11 percent.

A precinct-by-precinct breakdown of the vote shows that more American Canyon voters went for Caldwell than went for the other three candidates combined.

Of the roughly 1,900 votes Caldwell received, almost 1,200 came from American Canyon, which has about half the district’s registered voters. Only about 700 Caldwell votes came from Napa, Coombsville and other parts of the district.

Meanwhile, more than three-quarters of the votes Simpson received came from Coombsville and Napa. He won more than 1,600 votes overall and 1,260 in those areas.

Similarly, 1,055 of Jager’s 1,399 votes came from Napa and the unincorporated county area.

Jager received 344 American Canyon votes and Simpson won 382 votes in American Canyon.

Caldwell, Jager and Simpson said they were not surprised by the breakdown. “I thought it would split according to geography, as it did,” Jager said. Like Simpson, he lives near Napa.

Jager had the endorsement of retiring District 5 Supervisor Harold Moskowite, and said both the Simpson and Caldwell campaigns have approached him for his endorsement.

Jager, whose campaign theme was that voters should not give former police and fire officials the supervisor job, said he has not decided whom he will support now.

Highway 29 divide

In American Canyon, Caldwell received most of his votes from older neighborhoods west of Highway 29. More than 850 votes from precincts on the west side, where Caldwell grew up, went for the former fire chief. But he received only 450 votes from neighborhoods east of Highway 29, where most houses are relatively new.

Coffey won 337 votes in American Canyon — fewer than the Napa-based candidates — and 271 votes in Napa and unincorporated areas.

Coffey, who will appear on the ballot again in November as she seeks re-election to the American Canyon City Council, attributed her loss in part to an “underground movement in town” that did not want her to leave city politics.

“People didn’t want me to move on recognizing there is significantly more work to be done here as I have the established voting record of asking questions and following up on constituent issues,” said Coffey.
