That is certainly one way to look at it, I guess.Pretty good results for R's and Trump especially. D's might have had their blue wave without insane Kavanaugh campaign.
I'm not sure what others were expecting, but I'd call flipping the House (while taking back suburban educated voters, particularly women), making unwinnable Senate races closer than expected, getting an openly gay governor, and soundly winning the popular vote a blue wave in some form.
It certainly wasn't a mandate for the current president.
