We're in the middle of Presidential primaries, and it's kind of convoluted. I can think of some easy ways to improve the system.
#1. Shorten the process. Right now, states vote for the Presidential candidates, over a period of five months. That's way too long, considering that the general election is one day long. Maybe we could shorten the process to two months? The way it is now, all the states that vote in Months 4 and 5 don't have much of an effect on the process, as the winner is usually decided by then.
#2. As I said yesterday, most states vote the same way in every Presidential election. We might want to change the primaries, so the 7-10 battleground states are the first ones to vote. They have the largest say in the general election, so why don't they have the largest say in the primaries?
#3. No more caucuses. Those made sense, in the centuries before instant, wireless communication. Now, they're sort of a convoluted mess, which are infamous for having wrong results, and which sometimes depend on coin flips to pick a winner. Also, it seems that the Republicans and Democrats can't caucus in the same state at the same time, which is inefficient. Better switch them out for standardized polling!
