The strength of a party rests in the strength of the primary. The Republican party held a fair primary with diverse candidates and abundant debates whereas the Democratic primary was rigged. The Libertarian party had a robust set of candidates and debates but few watched.
To paraphrase Arrow's theorem, there does not exist a fully satisfactory election process. There exist many bad schemes that usually produce ridiculous results and there are a few good schemes (none of them perfect) that still occasionally produce ridiculuous results. Ridiculosity can be minimized by holding several rounds of elections, trimming the weakest candidates each round. The penultimate round should have exactly 3 candidates and the final round should have exactly 2 candidates.
An election with 2 candidates doesn't have pitfalls whereas pitfalls abound with more than 2 candidates. Pitfalls can be minimized by focusing on trimming the weakest candidates rather than on identifying the strongest candidates. Several rounds of gradual trimming can occur to narrow the field down to 1 candidate.
