All of that is true.
Balmer was described by his brother as a
political independent until
2024, when he tried to convince his family members to vote for
Donald Trump. In a warrant to search Balmer's possessions issued after the incident, state police stated in their search warrant that Balmer had targeted Shapiro based on "perceived injustices toward the people of Palestine". In a 911 call previously made by Balmer, he characterized Shapiro as a "monster" who should stop having his friends killed, put his people "through too much" and said that he would not take part in Shapiro's "plans" for
Palestinians.

And as for the Pelosi attacker...
In 2007, DePape started a personal
blog, initially writing about topics such as
spirituality and the natural psychedelic
ibogaine. In the months before the attack, DePape resumed writing on his blog after a long hiatus, this time on
conspiracy theories and
alt-right politics. In posts on
social media and at least two blogs, DePape espoused
far-right views, promoting
QAnon,
Pizzagate, and other
far-right conspiracy theories, as well as sharing far-right
Internet memes.

Party affiliation records note DePape to be a
Green Party member as of 2014; according to Taub, he was "more on the
far left than the
far right" during their relationship. Experts on extremism and terrorism say that such shifts in views – from left-wing fringe movements to the far-right – can be held as "side switching", a fairly common phenomenon among persons who are
radicalized online, who shift between "mutually exclusive or hostile ideologies" through "bridging areas" such as antisemitism, anti-government stance, and
misogynist beliefs.
