No amount of misinformation can constitute stealing an election, even if (as in the case oh so many Italian politicians) you literally own the media. People voting for someone despite being misinformed is them being comfortable with misinformation to the extent that it doesn't affect their vote. In that sense, it reflects the will of the people.
Even before the Information Age, there were ways of acquiring insight into the true functioning of government. After the Information Age, there is basically no excuse. People only don't see through misinformation because they don't want to or because it doesn't matter to them.
