Media in US are all owned by Zionist first rule over America agenda. Republicans are unencumbered by genocide support, while non-voters, and some DNC supporters are not. Both DNC and GOP are Zionist first rule supporters, but DNC needs credibility for some of its other talking points.
Media will support GOP because of their unanimous "finish the job of genocide" Israel support. So the GOP are certain that defending their medicaid/ACA cuts for corporatist/oligarchist supremacist tax cuts is a political winner. Media supporting GOP more, makes the game of blaming democrats for shutdown seem like having "2 aces in texas hold em" play/heavy bet to place.
