This is an actual “reason Democrats lose.” How this spectacle doesn’t get hordes of Democrats off their asses to head to the ballot box with a vengeance is beyond me.
Perhaps another way to look at this is from a relative standpoint, based on where the election cycle has been up until now. The whole "motivating them more [than before]" dynamic implies that people are even more motivated to vote than they were previously. Democratic enthusiasm to vote has been much higher consistently throughout this cycle; less room to improve or care more. In other words, a huge segment of Democrats can't be more motivated to vote than they've been for some time, so seeing more Republicans express motivation over this issue isn't surprising.
Of course, questions like these are pretty much garbage and impossible to quantify/judge with any level of accuracy or truthfulness...but given the GOP's deficit of enthusiasm and motivation this cycle, seeing higher figures from them on any one issue suddenly isn't necessarily out of the norm.
