A black civil rights advocate and former Tea Party activist jumped into the Republican primary to take on Rep. Steven HorsfordSteven Alexander HorsfordTwo former Nevada congressmen set for rematch What to watch in Tuesday’s primary elections Nevada Democrat accused of sexual harassment reconsiders retirement: report MORE (D-Nev.).

Niger Innis, a spokesman for the Congress of Racial Equality and former strategist for TheTeaParty.net, launched his bid on Wednesday, pledging to “shake things up in this district."

“We cannot afford go-along, get-along, soft, establishment Republicans or big-government, trickle-down Democrats,” he said, according to the Las Vegas Sun. “We must be willing to elect leaders who will advance private-sector innovation, entrepreneurialism and help liberate Main Street."

Innis framed himself as a grassroots candidate and brought substantial local support to his kickoff, with former Nevada Republican Party chairs Amy Tarkanian and Dave Gibbs and former North Las Vegas Mayor Shari Buck alongside him on Wednesday.

He’s also nabbed the endorsement of former GOP presidential contender Herman Cain, who had previously headlined a fundraiser for him.

Having moved to the state in 2007, he might need those local endorsements to compete in the primary, where he’s facing Cresent Hardy, a Mesquite assemblyman who is the favorite of local Republicans.

Horsford, who became the first African-American the state had sent to Congress after his 2012 win, has been targeted by national Republicans but is not considered particularly vulnerable heading into reelection.
