> In parliamentary systems, you might have a lot of parties in the mix, but they caucus and forms blocs. Same happens here, just upstream through primaries.
In our two party system, the lesser parties normally never get included in the legislative process. (those primaries effectively exclude them) In a parliamentary system any party that gets enough votes will get some seats.
If we adopted that sort of system you'd immediately see some greens and libertarians involved in the legislative process, and presumably you'd see an end to jokey pseudolibertarians in the Republican party, since everyone would just vote for the real thing. The "you're just throwing your vote away" disincentive would no longer exist. (based purely on how often that topic comes up in conversation during elections, I assume you'd see some big changes in the ideological makeup of the legislature)
