Not as in nuclear energy, but as in nuclear option.
Let's face it, it's ridiculous. And Democrats are partly to blame, because they played games blocking nominees by Republican presidents when they shouldn't have. But the Republicans in this Senate have pushed the nomination delays to a whole new bad level of bad, and it appears with increasing probability that we're going to have a nuclear showdown over filibusters.
While it's sad that grown men who should know better are behaving this way, it appears necessary for the proper governance of the country to rein in the out-of-control, abused filibuster power.
