Beyond the insanity of allowing Democrats to choose their opposition, what business does the State have spending taxpayer's money to play any role in choosing a private institution's nominees?
Why do we allow it?
Why do we allow the several Boards of Elections to record party affiliation with voter registration?
To facilitate our primary contests? Is that really a compelling state interest? If your candidate opposes public sector unions or a single plank on their platform, for example, is it really wise to allow any state bureaucracy any role whatsoever in the process that makes him a private institution's official nominee?
Why should a candidate's party label appear on a ballot at all? (Thankfully, a few states have eliminated straight-party voting.)
And I won't even begin to describe the presidential primary tournament. Republicans have allowed themselves to get screwed by this Rube Goldberg device every four years for decades, now. Each time, this unconstitutional madhouse vomits up a McCain, a Dole, a Romney, and each time Conservatives finds themselves marginalized before the snow melts each election year, afterward forgetting it was the merry-go-round ride that tossed them under the bus by the time the carnival returns four years later.
