Ten years of Wisconsin votes - effect of voting machines
My previous posts have considered correlations between voting machine use and the vote for Trump in 2016 in Wisconsin at the municipality and reporting unit level. In this post I will compare the results from 2016 to those in elections from 2008 to 2018, to see if the correlation of voting machines with the election results was a one-off, or if it is a common trend throughout the years. I also look at the results at county level.

The effect of optical scanners on reducing turnout in Wisconsin
The Optech Eagle optical scanner was recently decertified by Wisconsin Election authorities. Voter turnout in Racine county where this optical scanner was used (a county that was not part of the recount) was unusually low.

Republican vote 2016 with voting machines at reporting unit level
The use of voting machines in Wisconsin is statistically significant in increasing the vote % for Trump at the reporting unit level. The size of the effect suggests that voting machine use could explain up to a 13,000 vote swing to Trump (he won Wisconsin by approximately 23,000 votes).
