It's fortunate that they are wanting to do this for 2016, as a lot of RP people are switching to the dem party for 2014. Why? - in order to primary out gun grabbers - and I'm mainly talking about the state level, but also the federal level.
Doing away with caucuses would hurt us, ditto halving the number of debates. If anything, we didn't have enough debates. OTOH, I think regional primaries would probably help us. Romney bought NH, but he wouldn't be able to do as well if he had to advertize in 25% of the country and have the vote come down on the same day.
Perhaps we should start pushing instant runoff voting. it would help to get people to vote for the guy the like the best, but don't think is going to win - and voters are lemmings so vote for the guy they think is going to win. Done right, it could really change election dynamics.
Where we are really screwed is that we failed to keep our organizations together. We are going t be starting, basically from scratch next time and it will take time to build momentum.
