36. some numbers: votes vs senate seats

The columns are from left to right… Party, vote percentage for that one election, seats each party had, votes for that one election, and last… the CUMULATIVE votes each party received over the past 3 elections thereby covering all the current members of the Senate. Arrows indicate a clearly anti-democratic result...
