I’m kind of leaning towards the idea that the US government should offer secure IT services to campaigns, because this is a problem for the country, not just the people involved.

Like, a campaign alone probably cannot counter nation-state intelligence agencies acting against them.

And the problem is larger than just “a country might try to undermine someone’s campaign”.

Having damning material to blackmail a President would be a problem, even if the material comes from activity prior to time as a President. We do not want that.

EDIT: l’d also add that this isn’t just a problem for the US. Leaders in general, but particularly leaders of democracies, where popularity determines who holds power, face that as a risk factor.

It’s not an entirely new problem in the Internet era, but I think that the problems are tremendously exacerbated by having a lot of sensitive information living on very complicated machines connected to a globally-accessible network.
