Polls. He was at 30% in dec 2015. That article says he will dwindle based on the polls. He did the opposite. Polls in October 2016 had Clinton running away with the Presidency.What are you even trying to insuate with this? That his support will magically increase when he spent his his entire presidency with his approval in the range of 35-42%?!?
That article you linked literally means nothing because his support has always been at that level.
Polls 11 months out mean nothing.
edit:
You also proved my point that no one reads pass the title. Thinking it was about the 2020 election lmao
