"The boisterous partisan rhetoric during the funeral of Minnesota Sen. Paul Wellstone (D-Minnesota), who died in a plane crash before the 2002 elections, provoked a backlash that became known as the “Wellstone effect” and was a factor in the subsequent defeat of his replacement on the ballot, former vice president Walter Mondale. There were political overtones to the 2018 memorial service for Sen. John McCain (R), whose war heroism Trump had disparaged and whose service also took place in Arizona. But eulogist Joe Biden, then a former vice president, lamented: “All we do today is attack the oppositions of both parties, their motives, not the substance of their argument.” Since then, that divide has only deepened. As the memorial for Kirk so vividly demonstrated, the growing imperative for the movement that Trump started and Kirk helped elevate is not to bridge, but to conquer."
