CMV: The US should hold a one day "voting day" for primary elections.

I live in the US and given as how it is an election year, I think it is interesting to look back upon what happened over the course of this year.  In doing so you begin to realize that throughout the primaries, a significant amount of media discussion was about momentum, particularly in the Bernie Sanders campaign. A large amount of the discussion was about whether or not Sanders could amount enough momentum to overtake Clinton, while others said Clinton would have too much momentum to be overtaken etc etc. 

Point in hand, the key word here is momentum. I strongly believe elections should not be based off of momentum and who has the advantage in delegates starting off, but rather the policies, the character, the beliefs, and views of the candidates instead. 

However, this is something that easily can be remedied by the implementation of a one day national primary. 

Now, one might bring up the argument that candidates should visited states one but one before voting so the candidates can become better acquainted with the people, but this is an argument of the past. In today's world we are all connected by media, where's in times past candidates could not be seen giving a speech in one state by the entire nation. The united states has changed in the past to keep up with modernism, so why can't it do so again? With this argument beside, a one day primary doesn't mean the candidates don't have to visit individual states: it means that candidates should go to each individual state to get on a personal level with the people then have a voting day where people can vote without being pressured and influenced by the decisions and views of others. 


There may be underlying reasons that the US keeps the primary system the way it does, and I don't know everything, so I post this here to learn.

The current system has its flaws, but holding all primaries on a single day wouldn't work very well either.

Look at the Democrats this year. Sanders was relatively unknown before the primaries began. He had very limited resources, but he was able to focus them on Iowa and New Hampshire. Because he performed well there, he got more donations and exposure to mount a real campaign. If all states had primaries on the same day, Clinton would have won in a landslide, and voters would not have gotten a real choice.

On the Republican side, there were many candidates all splitting the vote. Over the course of the primaries, weaker candidates gradually dropped out until we settled on the candidate that was the will of the voters. If the primaries were all held on a single day, nobody would have been close to a majority. We would have ended up with a brokered convention, and it would have been decided by political wheeling and dealing rather than the will of the people.
