I thought you were a Libertarian, why should you be allowed to vote in a Republican Primary. People can and should be able to change their party affiliation. I think they should require the party change be made long enough before the primary that it isn't part of some opposition strategy.
A Person does not have to be a member of a respective party to vote in the primary ... the Uni-Party system wants it that way .
If people HAD to join a party and pay a yearly due . They could not get the turn out for the primary election that they do .
Also you would not need one ... just have the membership mail in a Primary ballot to the party HQ and shazam !! the primary is done without the taxpayers funding it . Of course you would not get the fanfare of the media ... when was the last time you herd of the Lions Club national prez . election on the tube.
Thanks
