About this archive

CheckSwing tracks federal political contributions by the principal owners of all 30 Major League Baseball franchises, sourced from FEC filings. Records are classified CONFIRMED or PROBABLE under a documented verification rubric; records matching a donor name but no other signal stay UNCERTAIN and do not enter the canonical dataset.
