Go read the whole damn thing, it's a textbook example of how radicals infiltrate. And remember, the indifference of ordinary citizens to monitoring local politics allows this to happen. Via the New York Times:
The man was one of at least a half-dozen current and former Proud Boys who have secured seats on the Miami-Dade Republican Executive Committee, seeking to influence local politics from the inside. Their ranks include adherents who face criminal charges for participating in the Capitol attack: Gilbert Fonticoba has been charged with obstructing Congress. Gabriel Garcia, a former Army captain who says he has left the group, has been charged with interfering with law enforcement officers during the civil disorder on Jan. 6, 2021.
The concerted effort by the Proud Boys to join the leadership of the party — and, in some cases, run for local office — has destabilized and dramatically reshaped the Miami-Dade Republican Party that former Gov. Jeb Bush and others built into a powerhouse nearly four decades ago, transforming it from an archetype of the strait-laced establishment to an organization roiled by internal conflict as it wrestles with forces pulling it to the hard right. The conflict comes at a pivotal moment for Republicans nationally, as primary voters weigh whether to wrench the party from its extremist elements — or more fully embrace them.
“Yes, we have fringe elements,” said René García, the chairman of the approximately 125-member Republican committee in Miami-Dade County, who is also a county commissioner and former state senator. “Yes, we have different points of view in our party. That’s how we are. And my job as Republican chairman is to protect everyone’s First Amendment right, however wrong they may be.”
