What's very funny about Fastbreak's idiocy is that how the Dems would usually fuck something like this up would've been to support McCarthy for nothing. That would've been consistent with their long history of loser behavior that has actually done more harm than good by hiding the truth about the Republican party from the public.
Since Trump was elected, but even really for a few years if not decades before that, the Democrats have been behaving as if the extremists in the Republican party were just a fringe element and that most of the Republican party were responsible adults who they just disagreed with on certain policy specifics. That enabled the media to cover politics in a "bothsides" frame no matter how extreme the GOP got, which helped enable the further radicalization of the GOP.
The Dems kept being the grown ups in the room because they thought it was the responsible thing to do and that being seen as doing the responsible thing would win them positive news coverage, but it never did. Instead, mainstream political media grew to expect them to cave to increasingly insane GOP behavior and actually criticized any deviation from that by Democrats. Meanwhile the GOP treated the Democratic party just like McCarthy has this whole year. So the Democrats have literally gotten nothing out of that loser behavior, it has actually often led to increasingly negative media coverage of them, and it actually enabled further GOP radicalization by preventing the GOP radicalization from becoming the real, unavoidable story.
They've finally broken from that loser bullshit. Now, as this circus drags on, it will become impossible for mainstream media to cover this as a typical "Washington dysfunction" story. The GOP's dysfunction and radicalization will be front and center, and the GOP civil war will provide a lot of juicy quotes attacking Republicans from other Republicans. And there is a fairly strong possibility that the Republicans can't agree on a replacement and that the more "moderate" members have to come crawling to the Democrats for their votes. Which would mean some sort of power-sharing agreement. And even if that doesn't happen and the GOP can agree on someone, they won't functionally be any worse for Democrats than McCarthy was because that's not actually possible. McCarthy was a completely untrustworthy piece of shit who never kept his word and was functionally controlled by the most extreme members of his caucus.
