The DNC posted a list of bills Kerry introduced and were enacted into law. He sponsored to enactment a total of 11 bills in his 20 years and I must say, it is a list of Great achievement:
Of those 11 bills, 4 designated special days or weeks with titles... 1 expressed solidarity with a family... 1 renamed a building... and 1 awarded Jackie Robinson a congressional Gold Medal... 2 appropriated funds for existing programs, 1 amended an existing act, and 1 reauthorized an existing program. *
Wow! What an accomplishment for 20 years in the US Senate. I'm impressed.
