I am curious about swing voters: voters who are undecided until close to the election and then make their choice based on how they feel. They are also known as floating voters. They have been declining due to partisanship. I have read that 16% of swing voters are liberal while 25% of voters overall were liberal in 2016. Is this a general trend about swing voters tending to be more conservative? (I am talking about federal elections from 2012 to 2018.)
