How can there be a vote with nobody there?

Harry Reid: Filibuster Changes Will Take Place In January

“Sen. Jeff Merkley (D-Ore.) has been working with Reid on the proposed changes, which would effectively force any senators wanting to delay a vote to visibly take to the floor and talk. Once every senator had left the floor and could no longer debate, a cloture vote would be taken that would require only a simple majority rather than two-thirds of the chamber in order to pass muster”

-  Quote from Huffington Post story on reforming the Senate filibuster rules.

Ok, let me see if I understand how this is going to work:

There is only one person left on the floor to debate and then they take a vote to cut off debate. Who the heck is voting? That one person? That would be a majority of one.

I thought a Senator had to be on the floor to vote, but I guess they now have early voting (they don’t?) and absentee ballots (they don’t?) or some other magical method to cast a vote without being in the Senate Chamber (i.e. on the floor).

It would seem to me, that the moment another senator returned to the floor, the debate would, in effect, be rejoined.

However, under Senate Majority Leader Harry Reid, this is how Congress works folks with a huge hole in logic and understanding.

Then there is the little matter of having a quorum of Senators present in order to have a legal vote.

And people wonder why our faith in the federal government institutions is being sorely tested.
