Now that sounds like a GREAT method if:
1. the voter can vote for one party
2. the voter can rank members within that party (say up to 3 members
to keep the ballot doable)
3. the voters' consensus ranking of members within that party is
decided using the Condorcet method.

I like it. A fair proportional representation system that is
precinct-summable, monotonic, and finds Condorcet winners within each
party's list.
