Judge Kavanaugh based on his track record as a Circuit Court Appellate Judge is not suitable for the Supreme Court. He has a track record of not following the law he didn't in the "Seven Sky" case (an Affordable Care Act case), in the "Garza" case (an abortion case) and in the "Agri Processor Company" case (an illegal immigration case). Whatever you think of Supreme Court holdings they're the law it's a superior court so as a Circuit Court Judge you follow their decisions and he didn't do so in numerous cases. How can the U.S. Senate confirm him you're supposed to be protecting America's legal system promoting respect for the law putting a Justice on the Supreme Court that he himself didn't obey the law why should District Court Judges and Circuit Court Judges follow the law when a Justice Kavanaugh didn't as a lower Court Judge?
Judge Kavanaugh as a Circuit Court Judge used cases before him as opportunities to apply for a job for the Supreme Court. In numerous of his cases they were like pages of a job resume demonstrating to far right groups and far right politicians he would be their champion on the Supreme Court. Human beings have the capacity to know what is going on everything doesn't have to be spelled out for them and if one reads some of his opinions with prudence one can pick-up on the truth that this is what he was doing. This is shameful beyond words because not only was he breaching his duty to interpret the law in an unbiased manner and be fair to the litigants and conduct himself in a manner that upholds the reputation of the Judiciary but he was seriously messing with peoples lives. In the abortion case where he gave the government more time to find a sponsor for the pregnant juvenile in the Office of Refugee Resettlement custody after the government had five weeks to place her where his extension would have ran her into the seventeen week of her pregnancy where the Texas state law had a twenty week limit and he didn't guarantee her a right to an abortion then but extended to the government another chance to block the juvenile from getting her abortion right. Someone with such a lack of caring for the law, the judiciary and other people is unsuitable for a seat on the Supreme Court!
Judge Kavanaugh is really scary radical and extreme in some of his views. America has numerous independent regulatory agencies that do important work for the American people and Congress in its wisdom made it so the members of the governing body of each of these agencies can only be removed for good cause. Judge Kavanaugh believes this is unconstitutional that all these governing bodies members should be at will appointees of the President meaning the President can remove them for any reason at all. His views here can be garnished from his opinion in PHH v. CFPB 881 F.3d 75 (2018). This would make all these agencies extremely political Presidents would be running these agencies to advance their political agenda. Imagine a President directly controlling the Federal Reserve Board to lower interest rates with the purpose of making credit more affordable to individuals and companies to help in the next election but ultimately creating asset bubbles, inflation and making the Fed unprepared to pull the country out of the next recession. The examples one can readily see would be disastrous for the American people. Judge Kavanaugh is not mainstream in this view and other views he holds and responsible people would definitely not put such a person on the Supreme Court. If the Senate does it will be making a mockery of the U.S. Constitutions "advice and consent" clause on Judicial nominees to the Supreme Court the Senate will have turned it into a completely political vetting process, if the nominee will do the majority's bidding on the Supreme Court the nominee get's confirmed - this will hurt America beyond words!
