The piece doesn't state that Republicans are evil. It states that they are knowingly (and possibly also unknowingly) sabotaging efforts to improve the American economy because of a difference in ideology and a refusal to agree with what most experts agree are the best courses of action.
Each of the "myths" listed have backing by polls of economists and other experts. Are you suggesting that all of these economists/experts are partisans?
It's obvious from the very first part of the article that's it's political hackery and drivel. This is the usual problem when you mix science (in this case economics) with politics. Political drivel and ideology gets justified with misguided or misapplied science as a backing.
This type of pseudo-scientific flim flam is more common in other areas (con men are experts at using it), but it's very much on display in this article. Cherry picking individual points, then using logical fallacies to apply them to policy, strawman arguments about the position from the evil republicans and on and on and on. Typical political hackery mixed with pseudo-science, basically just political spewing.
