Mack Miller, serving 5 to 15 years for theft, is using the Republican name to steer voters in Senate District 8, and George Harris says it’s personal.
During election season, mailboxes, phones, and news feeds are stuffed with endorsements. Some come from groups you know. Others come from groups you have never heard of.
A group called the “National Republican Chamber of Commerce” is putting out political endorsements in Nevada. It is tied to Joseph “Mack” Miller.
Right now, Miller is sitting in a Nevada state prison.
And in Senate District 8, one of the state’s most important races, this “Republican” group endorsed Democratic Sen. Marilyn Dondero Loop over Republican George Harris.
🚨 Joseph “Mack” Miller is in prison for theft, including $100K+.
Yet his “National Republican Chamber of Commerce” is issuing political endorsements.
In 2020, Nevada Current linked its website to a fake Democratic chamber endorsing conservatives.

Who Is Mack Miller?
Miller is a familiar name in local GOP circles. He ran for the Assembly in 2018 and 2020. He also ran for lieutenant governor in 2022 and lost the Republican primary.
In 2018, the Las Vegas Review-Journal reported that a military court found Miller guilty of deserting his Army unit during the Iraq War. Miller disputed that account, saying he left after an injury.
Then came his most recent conviction.
The Nevada Attorney General’s 2022-2024 Biennial Report lays it out on page 15. It says Miller “held himself out as an attorney” to a victim. He promised to set up a company with money from the sale of the victim’s collector car. Instead, he kept the money for himself.
Miller pleaded guilty to theft of $100,000 or more. He was sentenced in 2023 to 5 to 15 years in prison. He was also ordered to pay $1,427,950 in restitution.
Not His First Fake Chamber
We have seen this trick before.
In October 2020, the Nevada Current reported on a fake “Democratic Chamber of Commerce” website that endorsed conservative candidates. Miller, then running for the Assembly in a heavily Democratic district, was on its list.
The site’s “get involved” form sent back an automatic reply from an email address Miller used. Voters in his district also got text messages pushing the endorsement.
One read, “Mack Miller for Assembly, endorsed by the Republicans and Democrats.”
This year, the trick is flipped. A “Republican” label is being used to boost a Democrat.
Think of it like a knockoff handbag. From across the room, the label looks right. Up close, it is not the real thing. “Chamber of commerce” sounds official. But anyone can build a website and give it an official-sounding name.
Why This Matters to Conservatives
A man convicted of stealing from a victim should not be steering Republican voters.
When a questionable group borrows the Republican name, it hurts every honest candidate and the party brand. I
The stakes are real. Democrats control the state Senate 13 to 8. Republicans are fighting to flip seats in Clark County and stave off a Democratic supermajority.
The Real Pick in Senate District 8
Senate District 8 covers parts of Summerlin and Spring Valley. It is about as purple as it gets.
According to The Nevada Independent, 30 percent of its voters are Democrats, 29 percent are Republicans, and 34 percent are nonpartisan. Democratic Sen. Marilyn Dondero Loop won the seat by about one point in 2022.
The Clark County Republican Party, the real one, has listed its pick for the seat. It is the Republican nominee, George Harris.
Harris did not mince words about Miller.
“Mack Miller is a disgraced criminal who has zero credibility; he has had a vendetta against me ever since we trespassed him from the Ahern Hotel,” Harris told Nevada News & Views.
Harris is an Army veteran, a small business owner, and a former Clark County GOP chair.
Gov. Joe Lombardo has endorsed him, a strong sign of confidence from a governor who has fought hard for Nevada families. So have the Nevada chapter of NFIB and the Las Vegas Review-Journal.
Harris backs school choice, more police, and lower taxes. He also opposes special tax breaks for big corporations.
As he put it on Nevada Newsmakers, “We need adult supervision in government.”
What You Can Do
Check the source before you trust an endorsement. Look up the group’s name. Ask who runs it. If you want to know who local Republicans actually back, go straight to the Clark County Republican Party.
If you get a suspicious text or mailer, report it to the Nevada Secretary of State.
