First of all, "all counties were red/blue" is not what "unanimous" means.
I agree with you there.
Second of all, I don't think "ha ha your state is poor" is the grand slam argument you think it is.
Takes a lot of mental gymnastics to boil down all the listed differences as "state is poor". Unless you mean "poor" as in "in bad shape" and not "economically suffering". I'll assume you mean the former as that's the only way your argument makes sense.
I think it's more about how a state is voting against its own interests. There is NOTHING about the Republican platform that would improve any of the listed metrics. If anything, Republican politics would only further worsen an already bad state of affairs.
And of the off chance your initial argument was entirely economic, it's Democrats who want federal government involvement to help poor states.
