No, but you don't know if your transactions are actually safe, or even more so an election, if you don't trust these auditors. The people writing the code, running the servers, etc - you also need to trust them, and they are actually the ones handling your transactions or votes, the exact middlemen.

And again, in any fully electronic system, you need to take into account the whole system, not just one part of it. Maybe Bitcoin or Ethereum or whichever blockchain you like is indeed perfectly safe and very trust-worthy. But if I'm connecting to it to vote from a Windows PC that I last updated 5 years ago, then I'm still extremely likely to lose my private key to my money or have my vote cast for whoever Microsoft or the writers of all the malware I'm running likes best.

There is no way to make electronic voting safe. There will never be any way to make electronic voting safe. Any country doing it is playing with fire. Blockchain does nothing at all to change this one iota.
