Nearly 40 percent of the electorate self-identifies as "independent." Why should they pay for Republicans and Democrats to run elections which are, in most states, closed to anyone who is not a member of the Republican or Democrat party?
Last time I looked, just about every state was running a deficit and we know about the numbers at the federal level.
If any political party wants to hold an election, it should pay for it. And, if any political party wants to hold a presidential nominating convention, it should pay for that, too.
Ah! The car is ready. Put this edition of Mullings down as more sound and fury signifying nothing. And, I know you remember the beginning of that quote from your English Lit class - it is "a tale told by an idiot."
