145. There's theory. And then there is the practice.

The political practice, if it isn't already abundantly obvious, is very partisan.
Independents can caucus with a party but they're on the outside looking in.

There are the 6 bills Sanders introduced and got passed:
S. 885 (113th): A bill to designate the facility of the United States Postal Service located at 35 Park Street in Danville, Vermont, as the “Thaddeus Stevens Post Office”.
S. 2782 (113th): A bill to amend title 36, United States Code, to improve the Federal charter for the Veterans of Foreign Wars of the United States, and for other ...
S. 893 (113th): Veterans’ Compensation Cost-of-Living Adjustment Act of 2013
H.R. 5245 (109th): To designate the facility of the United States Postal Service located at 1 Marble Street in Fair Haven, Vermont, as the “Matthew Lyon Post Office Building”.
H.R. 1353 (102nd): Entitled the “Taconic Mountains Protection Act of 1991”.
H.J.Res. 132 (102nd): To designate March 4, 1991, as “Vermont Bicentennial Day”.

Nothing very exciting.

Democrats and Republicans want to promote a member of their own party to help them get political credit for the legislation and control their own policy for major bills. That's the practice.
