A negative slope is expected with random values, the point is the correlation between Republican straight party vote and Trump single vote is not random, you would expect it to be a fairly constant ratio, aka a straight line.
My argument here is that you wouldn't expect a straight line. It's a bit counterintuitive until you start playing with the numbers yourself. The problem is that the y-axis represents different in pct not a pct. So as the pct on the x-axis increases, the difference between the pcts will increase.
That's not true, the X axis is (# of people that voted straight party republican ticket option / total number of republicans and dems that voted straight party ticket option). The Y axis is (# of people that voted Trump but didnt vote straight party ticket option/ total # of people that didnt vote straight party ticket option) - X axis data. The Y and X axis are independent data sets (excluding the subtraction of the Xaxis data) , one does not include the other, one doesnt have to go down if the other goes up and vice versa.

The real world correlation says that as the X axis % increases, so will the Trump vote on the Y axis, thus negating it.
But the y axis isn't Trump's vote pct. Its the difference between his vote pct and the Repub vote pct. That's the big problem with the analysis.
