Missouri Senator Roy Blunt is joining his fellow Republicans in criticizing a push by Majority Leader Harry Reid that would limit the power of the filibuster -- a legislative technique to give power to the minority party.
Blunt and the GOP call Reid's proposed rule changes the "nuclear option." Reid prefers the term the "constitutional option."
Whatever you call it, it would limit the use of the filibuster by making a few changes – most notably being that the one doing the filibustering actually has to be present for the speech, and can’t just threaten it.
