That is possible.
The other serious related threat is that we don't know what's being said. With the way communication happens now, which is often over apps and other ways that don't allow us to keep track of what's being said, we have less of a window into what's being said. Related to this, there is less of an accountability mechanism, in that we have less journalism than we had in the past. We particularly have less local journalism, which follows what local candidates are saying.
Our capacity to see the whole conversation that's going on during elections and to see how much mistruth is present is more limited than it has been in the past. Even if politicians are no less dishonest and even if the share of the spread of misinformation is the same, our capacity to see it is arguably lower than it was before.
