Yes. Turn out for the election Franks won in 2016 was ~300,000 total votes. Turn out for this one was around ~174,000. Most of the decrease in turnout was by Republicans (a decrease of ~112,000 votes), but Democrats also had a decrease (~10,000 votes). The bottom line, to me, is that 2016 was a presidential election year, and Trump brought out a lot of voters. This time around turnout was less either because voters weren't generally aware of this special election, or weren't motivated to vote because of the Franks scandal or other reasons.
I guess the big question is...will the Trump voters turn out in the 2018 election?
I would hope that the general election will produce more turnout. You know the other side is fired up.
I’m truly hoping that some of the stuff about the Dems and this farce of an investigation of Trump comes out in October. It would be nice for the Republicans to use an “October Surprise” of their own for a change.
