Late last week, Grassley decided not to honor a Senate tradition of holding up hearings for judicial nominees who aren't cleared by their own home state senators. That tradition is known as the "blue slip courtesy" born out of time before nationwide communication technology when a given state's senators had access to much more information about nominees than their colleagues from the rest of the country. Grassley correctly noted that Democrats were now trying to use the blue slips tradition to replace the filibuster, and he's having none of that. As recently as last month, the Democrats and much of the news media's punditry were expecting Grassley, who is no fan of the president, to keep the blue slip tradition in place. But Grassley gave Trump this very special gift instead.
And that brings us to the Democrat who provided the initial generous source of President Trump's solid triumph: Former Senate Majority Leader, and Democrat, Harry Reid. Reid is a major reason this good fortune has befallen President Trump because Reid was the one who killed the filibuster rule for judicial nominees in 2013. And when he killed it, it was gone for good.
Republicans were powerless to stop a series of President Obama's judicial nominees after that. That is, until they won control of the Senate in the 2014 elections. The GOP may have failed at using that majority to achieve much, especially making even a dent in Obamacare. But they were able to freeze the Obama nomination process in its tracks, most notably by delaying and eventually killing Merrick Garland's nomination for the Supreme Court.
