LaFaver, a Democrat running for the Missouri House in Kansas City's 25th District, said he changed his mind when he began getting calls about a mailer from Holsman's campaign.
"These folks received some mail from Jason Holsman that had my picture on it and they wanted to know if I was endorsing a candidate in the Senate race," LaFaver said in an email to supporters. "Up to that point, I had told both candidates that I would stay out of their race. However, since I was dragged into the race with the latest mail piece, and enough people have now asked me the question, I feel it is necessary to tell you that my wife Stephanie and I are both voting for Crystal Williams for state Senate."
The endorsement, coming less than a day before voters go to the polls, is not an indictment of Holsman, as LaFaver notes that Kansas City is "lucky to have two candidates for Senate who will be good public servants."
But the edge goes to Williams, who "will fight tirelessly for the things that we hold dear," he said.
"At every step of the way Crystal has been a fighter for progressive causes and has triumphantly stood up to attacks against women and low-income children," LaFaver said.
Williams, a Jackson County Legislator and former nonprofit advocate and lobbyist, said she is particularly proud of LaFaver's endorsement.
"However, I am disappointed that my opponent resorted to the tired old tactic of implying endorsements he did not have," she said. "As is often the case when candidates resort to deceitful tactics, that strategy has clearly backfired."
Holsman, a three-term member of the Missouri House, said LaFaver was simply in the background of a photo of a public political event. He declined to comment on the endorsement, except to point out that LaFaver's campaign treasurer is also Williams' husband, Richard Speidel.
Another mailer getting attention in the 7th District race comes from a political action committee called "South Kansas City United." The ad criticizes Williams for what it refers to as "negative campaign tactics." It asks voters to "Vote yes on Jason Holsman."
The PAC was founded in 2008 by Sam Giannini. Of the $2,400 it reported raising on its first disclosure report in 2008, $700 came by way of a loan from Jason Holsman's campaign for the Missouri House.
Gianini lists 2511 E. Red Bridge Terr in Kansas City as his address. Holsman's current campaign treasurer is Judith Gianini, who lists the same address.
