This algoritm pragmatically computes how far left/right a senater's polical views are by placing them in the corresponding place on the page
1) How are abstentions counted? Does a senator that abstains more get pushed out towards the edge for having less connections in general?
2) If a party member votes 100% along the party line, then they will be towards the center of the blob. If a party member is less partisan in the fashion of voting WITH bipartisan consensus then that person is gets put in the center. If a party member is less partisan in the fashion of voting AGAINST bipartisan consensus then they would be on the edge far from the center.
