Moving the primary up to June (from September) makes sense. It makes sense that you don't penalize a party with a contested primary by making it just two months before the general election.

Of course, in a state where Republicans are struggling to be competitive in many elections, the one positive they have is that less competition in their primaries means they have a real shot at a weakened Democratic nominee, so they are unlikely to go along with this idea. This sounds like inside baseball to some, undoubtedly, but makes a real difference.
