Why should the courts wade into this? I can conjure many alternative reasons for Kavanaugh and others who wish to defer. Congress signaling an intention to take up legislation, for example - let it proceed rather than muddy the process with a ruling.
Notice that Kavanaugh objects only because there is not a specific grant of authority from Congress to CDC. IOW, Kavanaugh says the moratorium would be fine if Congress issued it.
This is why we're so fk'd. All these young justices went through the leftist Ivy League training camps and came out sentimental modernists and wind up TOOLs. I never could stand Kavanaugh after he blubbered like bitch on national TV.
Look at Gorsuch, reading faggotry where it was never intended. Barrett is a product of Notre Dame, which lost it's Catholic identity decades ago, and is nothing but a leftist goon factory.
These people are NOT going to save us.
