Radical rightwing movements can influence politicians to weaken democracy and support autocratic tactics. The theory of social movement partyism suggests that political parties and extremist groups can team up, leading to elected officials aligning with movement goals. A study found that members of Congress from districts with high levels of hate groups, especially those formed during the Trump era, were more likely to object to the 2020 election results. This shows that extremist movements influenced recent anti-democratic actions by elected officials in the United States.
