Not one federal official has ever conducted an election. Not one federal official has ever counted a vote. State and local elections are not stovepiped. There are national conferences of election officials where information and technology is shared. As far as fighting foreign interests is concerned, remember that Fusion Centers came from and were funded by state and local governments.
The fed track record wasn’t all that great prior to 9-11. It was fragmented and duplicative. We don’t disagree about election security. I don’t think the one basket of eggs theory works for elections and prefer the combined input of all people. People aren’t smarter just cuz they receive a federal pay check. If you like the single top down approach, there is nothing more to say.
50 different systems have 50 different sets of holes. I imagine our major corporations are fairly top down, I bet P&G has standards at all their plants, they do not tell Poughkeepsie to "do their own thing".
One thing I know about computer security is spreading information is good. If I see a phishing attack, I immediately alert my users. Right now, if Indiana sees a spear phishing attack, do you think they alert Colorado employees?
