Um, no. The Democrats began wholesale political filibusters on Bush II's nominees. They then abolished the filibuster on all nominations short of SCOTUS when they had the Senate to get through Obama's nominations when the Pubbies doubled down. Remember, when they had the Senate and the White House, they did not have the opportunity to rush through a SCOTUS justice. The Pubbies do, so once again they have extended a Democrat precedent.
It's important to remember that such well-known unabashedly liberal lions as Stevens (confirmed 98-0) and Ginsburg (confirmed 96-3) enjoyed full Republican support based on their qualification, even though their judicial philosophy and political bents were anathema to those same Republicans. Even Kagan, with zero judicial experience and an extensive background in liberal activism and Democrat politics, and "wise superior decisions Latina" Sotomayor were confirmed with significant Republican support. (Seven of thirty-one for Kagan and nine of forty for Sotomayor.) Yet since Reagan, Democrat Senate policy has been that any Republican nominee is automatically an extremist. Alito received only four Democrat votes and Thomas none, despite both being well-qualified and no more conservative than Stevens, Ginsburg, Kagan and Sotomayor are liberal. Finally, the GOP has begun matching them in political activism.
I won't claim it's a good thing because it isn't, but the Pubbies are following the Dems' lead here.
