OK. Let's do that.
The US population increased by 3% over that timeframe
And 3rd party candidates got 1.7% of the vote in 2012. In 2016, they got 5.7% of the vote.
So to answer your question, there doesn't appear to be any evidence that these extra voters were motivated to show up to vote for Trump, which is why he got less of a share of the vote than Mitt Romney
2020 went back to 1.9%... So that available 4% of voters didn't move to Trump either, as he still failed to outpace Mitt ****ing Romney
