"The U.S. Senate already has one Arlen Specter too many"

This quote by Marco Rubio is a recommendation to the late Senator Arlen Specter, who served in the U.S. Senate from 1981 to 2011. Specter was a Republican-turned-Democrat, and Rubio was a Republican senator from Florida. By stating that the U.S. Senate currently has one Arlen Specter too many, Rubio is suggesting that Specter's switch to the Democratic Party was a mistake, which the Senate would be much better off without him. Rubio is also suggesting that the Senate ought to not have anymore political leaders like Specter, who change celebrations for political gain. He is indicating that the Senate should be filled with politicians who are devoted to their party and its principles. In this method, Rubio is advocating for a more unified and consistent Senate, where celebration commitment is valued over political usefulness.
