Not really, if you read the article it only defines political violence as violence that isn’t done by the state:

That figure underscores just how much the spate of attacks — from the assassination of conservative activist Charlie Kirk earlier this year to the attempts on President Donald Trump’s life in 2024 — have rattled the nation.

In addition to Kirk’s killing and the attempts on Trump’s life, there was the gruesome attack targeting former Democratic House Speaker Nancy Pelosi that left her husband, Paul Pelosi, with a fractured skull in 2022; the assassination plot against Supreme Court Justice Brett Kavanaugh that same year; the plan to kidnap Michigan’s Democratic Gov. Gretchen Whitmer in 2020; and the firebombing at Pennsylvania Democratic Gov. Josh Shapiro’s residence earlier this year.

In June, former Minnesota House Speaker Melissa Hortman and her husband were shot and killed in their home by a man impersonating a police officer in an attack that Gov. Tim Walz (D) called “politically motivated.” The man accused of killing Hortman and her husband was indicted on federal murder charges. His case is still pending.

Etc etc.

Political violence has been with us long before politicians started getting shot, but political motivations didn’t count before because it was the government doing it.
