They should make a statement like "The Constitution requires the Senate to carry out its role of advise and consent. The Senate has failed to carry out their Constitutional responsibility. While Secretary Clinton and I both have the utmost respect for Judge Garland and believe he is extraordinarily qualified, the Senate has shirked its duties using the argument that the Next President should make this choice. This election is being contested, in significant part, based on what kind of Supreme Court the American people want in our future. Therefore, if Judge Garland is not seated before Election Day, I will withdraw his name from consideration, leaving that choice to Mr. Trump or Secretary Clinton as the case may be."

In other words, force their hand.

I'd love to see that smirk disappear from Grassley and McConnell's faces if that happened. I'd even pay admission.
