Republican nominees to the court follow the intent of the judiciary Branch, routinely swinging the vote right or left depending on the laws passed by Congress as it pertains to the Constitution.
On the other hand, the Democrat Justice nominees are ACTIVISTS. They ignore their jobs in favor of Social Justice initiatives popular at the time.
Obama already tried destroying the Executive branch by setting the precedent that the President can pick and choose which laws can be enforced. Now the Dems want to do it again to 2nd branch of government.
