Senate Filibusters

I read Lindsey Graham saying there’s no chance for 60 votes to pass climate change legislation.   People have written in support of the filibuster, because it protects the minority party, but the problem is the Democrats rarely have the cajones to use it, and the Republicans do it as standard procedure.

Besides, it’s unconstitutional:  I looked and found this in Article I, Section 5:

Each House shall be the judge of the elections, returns and qualifications of its own members, and a majority of each shall constitute a quorum to do business;

Last time I looked, “majority” mean 50% plus 1.  The filibuster blatantly contradicts this, not to mention personal holds.

Someone should suit the Senate and force them to abide by the constitution.   Who has standing for such a lawsuit?
