"The Progressive Caucus would prefer a single-payer system -- 99.9 percent of the 80 members have said they would vote for a single-payer system" from this article
This is ridiculous. It is impossible to get 99.9% of 80 people. If all 80 members vote for something, than the percentage is 100%. If one of the members objected, then the support percentage would be 98.75% Clearly math has no meaning to these people. They must have thrown around that number just because they thought it sounded impressive.
