The Freedom Caucus has blown up budgets, forced a speaker of the House into early retirement, and recently torpedoed President Trump's efforts to overhaul Obamacare.
Though present at almost every major legislative turn in the past two years, they're still the obstructionists that nobody knows, and that obscurity gives them an advantage.
Because eight out of every 10 adults know "little" or "nothing at all" about the Freedom Caucus, according to recent polling, the faction has managed to fly under the radar. That allows the roughly three-dozen conservatives to throw sand in the gears of Republican leadership then retreat into relative obscurity.
This phenomenon was on full display during the repeal and replace debate. Outside the Beltway, it seemed like Republicans just couldn't get their act together. Inside Washington, the Freedom Caucus was largely blamed for bringing the bill down. Since then, criticism of the faction has reached a high tide. They've been cursed by staffers, condemned in editorial pages, and called out publicly by President Trump.
But like trying to shoot a bug with a bazooka, none of it has worked, and none of it increased their profile.
According to a new poll by the Pew Research Center, 42 percent of the public says they've heard "nothing at all" about the group while another 39 percent report "a little" familiarity. Only 19 percent say they've heard "a lot" about the faction.
Put another way less than two out of ten Americans have any real idea about the small band of conservatives that play an oversized role in shaping national politics.
Of course, this could change. While Freedom Caucus members love the D.C. spotlight, they're not likely to break the nightly news unless some major crisis occurs. A government shutdown, like the one looming at the end of this month, for instance, could do the trick.
