It is very simple. If they vote to invoke cloture… to close the Senate debate on the nomination of Gorsuch to the Supreme Court, they are voting for the validation of this President and this Presidency. They are voting to validate the Republican strategy of stealing a Supreme Court nomination from President Obama. They are voting to legitimize and normalize the Russian intervention in our political system.
They are putting a black mark on their respective records. A black mark that they must never be allowed to live down.
