Question

Just what exactly is a roll call vote?

Answer 1

the vote of each member is recorded (name and vote) as opposed to just a tally of y/n votes.

Answer 2

The 'roll' is the list of members in a class, a deliberative body (such as the Senate) or any other organization.

In a roll call vote, each member's name is called out and each member says out loud how s/he is voting.
