The result is a nation on edge, two presidential efforts poised to spend $1 billion on advertising to demonize each other and 112 days until the polls close.
“This country over the last several years has gone from being polarized to being polarized and radicalized,â€� said Michael Jensen of the University of Marylandâ€
The former leads to gridlock, he explained, the latter to violence.

Investigators said they had no information Sunday about the motives of the shooter, whom they identified as a 20-year-old with no known history of violence, little to no social media profile and no significant involvement in political causes. Authorities said his bullets had killed a man in the crowd and injured others, including Trump, whose ear was bloodied.
The tenor of the campaign trail had been transformed long before the shots rang out Saturday in Butler, Pa. Gone are the soapbox saws about “our childrenâ€
“Donald Trump is a genuine threat to our nation,â€� Bidenâ€
Trump has encouraged violence against protesters at his own rallies and calls those who were convicted of participation in the 2021 attack on the U.S. Capitol “hostages.â€� He has described his political opponents as “verminâ€� and warned that the nation would face terminal decline during a second Biden term. “If he wins this election, our country doesnâ€
Prominent Democrats have been nearly universal in condemning Saturdayâ€
“Unity is the most elusive goal of all, but nothing is important than that right now,â€� Biden said in a White House statement Sunday, after meeting with his team investigating the shooting. “Weâ€
Trump has told his team to focus programming for the Republican National Convention, which begins Monday, on a theme of “unity.� His advisers have suggested to speakers a need to “dial it down, not dial it up,� according to a person who has spoken with Trump and who spoke on the condition of anonymity to discuss private conversations.
But grievance remains the dominant currency of American politics — the conviction that one side has been victimized by the other. There was little evidence on Sunday that calls for greater understanding across party lines had filtered down to the grassroots — or that any softening of divisions would last.

A YouGov survey conducted Sunday described the contours of a rattled nation. Two out of every three respondents said the current political climate makes violence more likely, while 8 out of 10 said political violence is a problem.
The share of Americans who support the use of force for political ends remains much smaller. One research project by the Democracy Fund found that 2 percent of Democrats and 4 percent of Republicans consistently justified violence for political ends in surveys between 2019 and 2022. More than 8 in 10 Americans said violence for political goals was never justified.
Whether rhetoric from candidates or campaigns directly influences violent acts is a more complicated question.

The man who shot President Ronald Reagan in 1981 said he aimed to impress a Hollywood actress. The 22-year old man who shot Rep. Gabby Giffords (D-Ariz.) in 2011 was later diagnosed as a paranoid schizophrenic. One of the two attempts on President Gerald Fordâ€
Robert A. Pape, a professor of political science at the University of Chicago, has been studying political violence for decades and surveying Americans on the topic for four years. His research finds little direct correlation between social media use and support for the use of force to achieve political ends, since most people still get their news from major news organizations. He argues that a deeper upheaval is gripping the country, turning policy debates into more existential contests.
“What is underlying this are more likely major divisions about where the country should go,� he said. “We are in the next 10 years about to go from a White-majority democracy to a multiracial democracy.�
Those tensions, he said, drive the divisive rhetoric around racial justice and immigration that animates much of this yearâ€
“There is this feeling that this is a divide about what America means, and we donâ€
Biden supporters have focused on rhetoric from the right, like a quote from Kevin Roberts, the head of the Heritage Foundation think tank, who said in a statement in early July that the nation is “in the process of the second American Revolution, which will remain bloodless if the left allows it to be.�
Roberts said he has “made clear that patriotic Americans were committed to a peaceful revolution at the ballot box, but the Left may commit violence to stop them.�

Roberts said that sort of rhetoric has “now led to murder and grieving families.�
The Biden campaign said in a statement that “in a moment when Americans should come together and unite to condemn this horrifying attack, anyone — especially elected officials with national platforms — politicizing this tragedy, spreading disinformation, and seeking to further divide Americans isnâ€
What concerns those who study political violence is that the public tensions and fighting have a way of filtering into deluded and unstable minds, indirectly leading to violence.
“This isnâ€
There is little indication that an attempt on the life of a former U.S. president and the presumptive Republican nominee will change that recipe anytime soon.
But in a best-case scenario, researchers hope it forces people to reconsider their behavior.
“This is a reckoning for political leaders and for ordinary Americans,â€� said Cynthia Miller-Idriss, who leads the PERIL extremism research lab at American University. “Itâ€
