WASHINGTON - It's been romanticized in classic film, gone viral on social media and become must-see TV.

• Jimmy Stewart stood all night in the Senate chamber against the wicked ways of Washington as the elected innocent in 1939's "Mr. Smith Goes to Washington."

• Texas Democratic state Sen. Wendy Davis, running shoes and all, staged an 11-hour talk-a-thon last week against a state abortion measure and became an Internet sensation.

• Sen. Rand Paul, R-Ky., enthralled C-SPAN viewers in March with a nearly 13-hour filibuster to protest any potential use of drones against U.S. citizens on U.S. soil.

Arcane but often effective, the filibuster is hot these days. But is it any way to run a government?

The battle over the use - or abuse - of the filibuster in the U.S. Senate may come to a head this month as Majority Leader Harry Reid, D-Nev., considers changing the chamber's rules to prevent Republicans from using the procedure to block President Obama's judicial and administration nominees.

How the chamber handles a spate of nominations this month may dictate whether Reid pursues the so-called "nuclear option" to allow the Democratic-controlled chamber to confirm nominees with a simple majority. Democrats have 54 votes out of 100 in the Senate, plus the steady support of two independents.

Odds are that the filibuster will remain intact. Democratic senators know they could soon be in the minority and need the protection of the filibuster. Reid himself didn't like the idea when then-Senate Majority Leader Bill Frist, R-Tenn., toyed with the nuclear option in 2006.

"A filibuster is the minority's way of not allowing the majority to shut off debate, and without robust debate, the Senate is crippled," Reid wrote in his book "The Good Fight: Hard Lessons from Searchlight to Washington."

Still, Reid might try.

"The Senate is broken and it's breeding cynicism across America, and we need to do much better," said Sen. Jeff Merkley of Oregon, one of a handful of Senate Democrats who have been agitating for significant changes in filibuster rules.

"There are a lot of nominations that are in the pipeline to be considered after the immigration bill. If there is extensive obstruction of the process in considering those nominations, I think that will fuel a major debate."

Several of Obama's top nominations still are pending in the Senate, including those to head the Environmental Protection Agency, the Department of Labor and the Consumer Financial Protection Bureau. Also, the nominations of three judges for the U.S. District Court of Appeals for the District of Columbia are in the early stages of the confirmation process.

Republicans accuse Democrats of trying to manufacture a filibuster crisis as an excuse to go nuclear. They say Obama's Cabinet nominees have been confirmed or are in the process of getting there, and that only a handful of judicial nominations are awaiting confirmation by the full Senate.

Overall, there are 100 vacancies at the circuit and district-court level, 33 with nominees, according to the Alliance for Justice, a group that tracks judicial nominations. Of the 33 nominees, 22 are awaiting Senate Judiciary Committee hearings, six have had committee hearings and five are awaiting Senate floor confirmation.
