My post 42 tells you why you are correct.
Yes. For raw numbers: In 2008, the Democrats outdrew the Republicans, 35.5 million to 20 million. And the Republican participation fell even further in 2012. In 2016, the Republicans just about tied the Democrats in turnout at 30 million, which represents a large drop for the Democrats since 2008.
Sure, you could argue that some of the turnout was prompted by anti-Trump voters, but Trump’s supporters alone still out-numbered the top TWO vote-getters in 2008 or 2012. Or that Trump had 42% more voters than Romney or McCain, while Clinton had 4% fewer than she had last time when she lost, despite winning with 55% this time.
