Politically motivated murders are receiving a lot of attention and dividing us further as many blame a political party or ideology. Some context from the libertarian think tank, the Cato Institute:
“Right-wingers are the second most common motivating ideology, accounting for 391 murders and 11 percent of the total. The definition here of right-wing terrorists includes those motivated by white supremacy, anti-abortion beliefs, involuntary celibacy (incels), and other right-wing ideologies.
Left-wing terrorists murdered 65 people, or about 2 percent of the total. Left-wing terrorists include those motivated by black nationalism, anti-police sentiment, communism, socialism, animal rights, environmentalism, anti-white ideologies, and other left-wing ideologies.”
Politically motivated murders since 1975:


And from the Center for Strategic and International Studies (CSIS-rated center, least biased)
“In recent years, the United States has seen an increase in the number of left-wing terrorism attacks and plots, although such violence has risen from very low levels and remains much lower than historical levels of violence carried out by right-wing and jihadist attackers. So far, 2025 marks the first time in more than 30 years that left-wing terrorist attacks outnumber those from the violent far right. Despite its decline this year, right-wing terrorism could easily return to previous high levels. It is important to resource counterterrorism efforts against both right- and left-wing terrorism and work with communities to gain their support against extremists. Leaders across the political spectrum must condemn violent extremism of all kinds, denying it legitimacy and reducing its appeal.”
“Our analysis of terrorism trends in the United States shows that, indeed, left-wing violence has risen in the last 10 years, particularly since President Donald Trump’s rise to political prominence in 2016, although it has risen from very low levels and remains much lower than historical levels of violence carried out by right-wing and jihadist attackers. More contentious politics in the United States and the expansion of the Make America Great Again (MAGA) movement appear to have reenergized violent left-wing extremists.”
