The candidate, one of four in the primary race for state Rep. Harold Dutton’s seat, received enough votes to help force Dutton, a longtime Houston Democrat, into a runoff this year.

“We are concerned that more than 2500 Harris County voters may have been duped into voting for a non-existent candidate, a serious theft of those voters' most important right, and three legitimate candidates were harmed by the crimes committed,” reads the March 18 letter, which was signed by every delegation member except Dutton and released to a Tribune reporter on Thursday. “We request that your offices coordinate an immediate investigation into the events documented in the attached memo and take appropriate prosecutorial action at the earliest possible time.”

Dutton was the only Democrat from Houston not to sign the letter.

Offices for District Attorney Kim Ogg and County Attorney Vince Ryan did not immediately respond to a request for comment by The Texas Tribune.

The issue at hand centers on the candidacy of Natasha Ruiz, who was one of four names on the ballot in the Democratic primary for House District 142, a seat Dutton has held since 1985. Dutton, who received about 45% of the vote, was forced into a runoff with Houston City Council member Jerry Davis, who got 25%. Ruiz, who was absent from the campaign trail, received about 20%, while Richard Bonton, who ran for the seat in 2018, received nearly 9%.

The day after the election, ABC13 in Houston said it called the phone number listed for Ruiz in her candidate filing. The woman who answered identified herself as “Natasha Demming” — a truck driver in Colorado who did not know why her name would have been used to sign up to run for the House seat.

The person at the listed number has not responded to multiple text messages and calls since the report first surfaced in March. On Thursday, someone answered the line, but hung up after a Tribune reporter identified herself and requested a comment.

Dutton, who had previously said he had hired a private investigator to look into the matter, told the Tribune on Thursday that he was not involved with the delegation’s letter to Ogg and Ryan and was focused on winning the runoff election, which is now slated for mid-July instead of May.

“I hope someone takes a look at the system that allows this to happen and cleans it up so that it can’t happen again,” he said. “If there are people who have engaged in a conspiracy, I hope that law enforcement will deal with them in the proper context.”

The delegation’s letter also included an attached “Indices of Election Fraud,” which detailed the background of the long-winding drama and “known facts indicating election fraud.” Those details included a mention of Marc Malacoff, who works for the Harris County Democratic Party and notarized Ruiz’s candidate filing paperwork, which was reviewed by the Tribune in March.

Ruiz’s application stated that it had been received and accepted by the local party on Dec. 9, 2019 — though Malacoff later acknowledged that he had made an error in his notary book by initially putting Nov. 9.

DJ Ybarra, executive director for the party, told the Tribune on Thursday that the local party wants to be transparent and is “happy to work with anyone who wants more information.”
