In 2016 I went to a workshop for people interested in becoming delegates to the Democratic convention and I think I even posted about it here. I found out that the delegates have to pay for their own travel, hotel, and other personal expenses and a potential delegate needs to gather 250 petition signatures to have their name appear on the ballot. Veteran delegates said that potential delegates team up in groups of 5 and each goes door-to-door to get 50 Democrats to sign each of the petitions. I could do all of that and still not be chosen because the party is prioritizing the choice of women and people of color, which is fine with me, but I decided not to pursue it.
I also got the chance to ask what goes on at the convention for delegates and what makes it worth going to. The veteran delegates told us it was a great networking opportunity to get to know elected officials, campaign workers, and delegates from other states. Outside of the convention hall were lots of parties sponsored by lobbyists and corporations. My feeling about attending a convention is it's for people who have too much time and money on their hands, elected officials and people who are considering running for office, and people who work in nonprofits who have to coordinate with local government or people who in their business can profit by having political connections.
I gave up watching conventions years ago. The convention atmosphere felt too frivolous and inauthentic and I never felt the speakers were speaking to me. If someone said or did something newsworthy I'd find out about soon enough on the news. The fights over the party platforms never felt meaningful. If the candidate makes it into office the last thing that goes into decision making is the platform from the convention.
2016 opened my eyes to something else - the conventional wisdom as far back as I can remember is there are 3 signs to tell who will win a presidential election: who has the better convention, who wins the debates, and who is better at fundraising. Hillary came out way, way ahead in all three and lost the election. More than anything this dampens any enthusiasm I could have for the convention.
That said, from what I read about the Democratic convention they did an exceptional job of relating to people watching and being in tune with what is happening in the country. There was no need to go bombastic to rile up a live audience or insert applause lines to speeches. People appeared from their own homes dressed less formally that they would need to in a convention hall. Without a need to bring speakers to the convention they could have a much broader range of speakers. And the nomination roll call was cited especially as instead of having a delegation head yelling above the noise of a raucous audience there were remotes from each of the states showing the great diversity of the country.
I don't know what the Republicans are going to do and from what I have read of their preparations they really don't know either. Republican governors now have a lower standing in the party than Fox News personalities. The party committee already released their platform which is to support whatever Trump wants, and since he is so erratic, that means they have no platform at all.
