Its a procedure in congress, There has to be agreement to bring something to a yes or no vote, That is called the Quorum. It dates back to the Roman Senate I believe.
A quorom is the minimum number of Senators that need to be present to have a vote. It is also used as a stalling tactic since a voice count of every Senator present is required.
The ROMANS tHAT SAME GROUP THAT BROUGHT YOU pater familia... THE PATRIARCH OF A FAMILY HAD THE rIGHT UP TO 2 WEEKS AFTER a birth or anytime during gestation to end the Life of the innocent baby if the patriarch deemed it unworthy to join his family!!
today we have abortion , partial birth abortion and Florida post abortion treatment!the mother is the only one with a say.. thus now Mater familia!
