Note added 2015_03_01: While updating the Senate cosponsorship leader board through the end of February, it became apparent to me that an error on congress.gov was replicated in my data for S.J.Res. 8, . . . providing for congressional disapproval . . . of the rule submitted by the National Labor Relations Board relating to representation case procedures. It appears that congress.gov entered each original cosponsor twice, and each subsequent cosponsor once. This made it appear as though the bill had 95 cosponsors, all of the Republican, which clearly cannot be, and I should have caught that. The error was flagged to LOC by web comment form on 2015_03_01. It is corrected for purposes of http://218and51.com on the cosponsor leader board posted on March 1, but is not corrected below. — Adam
