Two days ago we wrote about the SAVE act which aims to prevent non-citizens from voting, citizens from voting multiple times using false identities, and vote fraud generally. As we noted, most Americans favor the act's provisions, yet it hasn't passed thru Congress and ended up on the President's desk.
Senate Majority Leader John Thune, who favors SAVE, has said he hasn't the votes to pass it, and has been widely criticized for his comment. Writing for Hot Air, Duane Patterson does a good job of explaining why Thune is correct, concerning the "talking filibuster" ploy.
To pass it would require dumping the Senate's long-standing rule requiring a supermajority (60 votes) to shut off a filibuster. This the Republican majority could do with a simple 50+1 majority.
So why do quite a few senators refuse to take that step? Senators tend to be long-serving. Senators who are reelected even once serve during at least 3 presidential terms. They know it is likely they'll end up in the minority at some point and that the 60 vote rule is all that keeps a 'trifecta' administration* from going crazy and destroying the country, doing stuff like nationalizing all private property, or conversely banning abortions nationwide.
It seems Democrat senators are willing to act against majority opinion in this case because they know the issue isn't topmost in their voters' minds.
*My term for when one party has majorities in both houses of Congress and has the presidency.
Afterthought ... I'm certain it has occurred to many senators that one of the primary roles of the Senate is to keep US enacted policy in the middle of the ideological spectrum. To damp down extreme impulses that may temporarily electrify the populace.
