What are the Arizona laws on primary voting? Is it possible that a large number of Democrats are crossing over to support Juan? After all, he only won his home state by about 53% in 2008, didn’t he?
I don’t know, but primaries should be closed and you make a good point.
I researched this a couple of months ago. No, registered Dims cannot crossover and vote for McCain in the Republican primary. But those registered as Independents can vote in any primary they chose. I forget the exact percentages, but there are around 30% or so percent of Arizonans registered as Dim, Republican and Independent. Pretty even.
So, the question is how many actual Dims or Republicans are registered as Independents so they can crossover and make mischief in another party's primary?
And, Independents cannot vote in the Libertarian primary races. The Libertarian won that exception, as they as so small that crossovers could totally dominate their voting if they ever want to do that.
