There it is, there's the thing they're really railing against. They wanted every Republican voter to vote for all of the Republicans, then all (or none) of the Democrats. Basically turning the ballot into RvD.

But they forgot one crucial thing: people. Even within the party, there are members and candidates others can't stand. And if you're going to give people choices, you have to be prepared for them to make choices you don't agree with.
