David Frum in The Atlantic:
The smart play for Trump is to postpone the nomination to reduce the risk of Democratic mobilization, and to warn Republicans of the risks should he lose. Trump’s people do not usually execute the smart play. They are often the victims of the hyper-ideological media they consume, which deceive them about what actually is the smart play. This time, though, they may just be desperate enough to break long-standing pattern and try something different.
Will the conservative legal establishment play ball?
The judicial status quo enormously favors conservatives. Even should Democrats win big in November, it will take many years for them to catch up to the huge Republican lead in judicial appointments. By then, who knows, the GOP may have retaken the Senate, and of course it may well find a way to hold on in 2020. But a last-minute overreach by McConnell could seem so illegitimate to Democrats as to justify radical countermoves should they win in November: increasing the number of appellate judges and Supreme Court justices; conceivably even opening impeachment hearings against Justice Brett Kavanaugh.
McConnell may want the win badly enough to dismiss those risks. But many conservative-leaning lawyers in the country may be more cautious. And their voices will get a hearing in a contentious nomination fight—not only by the national media, but by some of the less Trump-y Republican senators. This could be enough to slow down a process that has no time to spare. Mitch McConnell has gotten his way so often that it’s hard to imagine he might ever lose. But the political balance of power is shifting this fall, and for once, McConnell may be on the wrong side of a power dynamic.
