Because he knows the Republicans will lose Congress in November and will begin his new phase of being a fiscal conservative again. He will then start attacking Democrats for wanting to expand the deficit and debt by handing out free money to Americans. Mark my words, that is exactly what he will start doing the moment the Republicans lose the Senate.
He wants chaos, so he can keep shoving through heinous legislation under the cover of a shit show. Why care about 1000 cuts when there’s a samurai sword sized problem to keep arguing over? This is an evil distraction and he doesn’t care cause he will die within a few years of age.
