Rich Lowry of National Review Online ponders the impact of the recent Supreme Court controversy on Donald Trump’s brand of politics.

The attempted political assassination of Brett Kavanaugh is bad for the country, but good for a Trumpian attitude toward American politics.

The last-minute ambush validates key assumptions of Donald Trump’s supporters that fueled his rise and buttress him in office, no matter how rocky the ride has been or will become. At least three premises have been underlined by the tawdry events of the past couple of weeks.

First, that good character is no defense. If you are John McCain, who genuinely tried to do the right thing and carefully cultivated a relationship with the media over decades, they will still call you a racist when you run against Barack Obama. …

… If you are Brett Kavanaugh, a respected member of the legal establishment who doesn’t have a flyspeck on his record across decades of public service in Washington, they will come up with dubious accusations of wrongdoing from decades ago when you were a teenager. …

… Second, that the media is an unremitting political and cultural adversary. In the Kavanaugh controversy, the press has been wholly on the other side, presuming his guilt and valorizing his accusers and their supporters. …

… Third, that politics isn’t just rough-and-tumble; it’s red in tooth and claw. Process and norms are nice, but they go out the window as soon as something important is at stake, like a potential fifth vote on the Supreme Court to overturn Roe v. Wade.

Senate Democrats may delicately talk about the importance of norms and civility on Sunday shows, but watch how they act.
