Perhaps I am a little bit biased by the situation in Germany. In the past years there was an increasing number of non-voters in elections (typically people who are dissatisfied with the political system). Now in the last years a rather right-wing populist party (AfD) appeared that convinced many of these non-voters to vote for them.

Compare this a little bit to the fictional situation as if Donald Trump would bring many people who did not vote in the last presidential elections back to the ballot boxes to vote for him.
