CCS

Support instant round robbin voting (Condorcet), which elects the candidate who would win every head to head race. Next best is Approval voting, which lets you vote for your favorite, or two you like equally, in addition to the lessor of evils you think you have to vote for, so you don't split votes like the current voting system. The major parties will always have power if voters are afraid to vote for any other than the big lessor of evils.
