Wow Grace... That is a late date for a primary. Ours was in April. I actually registered as a "R" for the first time in years because there was guberantorial candidate I really liked. He lost. So, it will most likely be business as usual in PA. But on the bight side, they had a box on the form for "do not bug me" and so far, so good.
It would be on the state Libertarian party to organize a primary. Get on your local's to make it happen.
Any other states have primary's this late?
