The past three years of widely-reported Federal court cases with political overtones have blown CJ Roberts' claims of an "independent judiciary" to smithereens. EVERY SINGLE CASE where a lower court has come down against a Trump Administration policy or initiative, it has been a Leftist judge appointed by a Democrat President, usually O'Bama. And virtually all of those cases have been reversed on appeal - with many more to follow, I assure you.
The Left has bent, folded, and mutilated "Constitutional Law," and the percentage of Americans who have any clue what the Constitution actually says (and doesn't say) is sinking into single digits.
And up until now, the Federal Courts have not been helping matters at all.
One more reason why one must say, "God Bless President Trump!" He has done more to restore the Constitution with his appointments than ANY previous President, Reagan included.
