I'd put them much higher than they used to be, at least in the United States context. Mis- and disinformation on social media platforms have been tied to encouraging the January 6 atrocities at the United States Capitol. That's an example of how mis- and disinformation about the results of an election can foment political violence.
There are also a high number of mis- and disinformation behaviours that occur around elections, such as trying to target particular populations, telling them the wrong day for an election or telling them rules about what they have to do when they vote that aren't accurate, and those sorts of things. Those are all dangers to free and fair elections.
