So why does anyone care if the Steele report was used in the FISA application?

17. That's all they could find in probe that involved any connection with Dems and Clinton campaign

Nothing else in the Russian investigation involves Democrats because John McCain, Peter Strzok (who voted for Kasich in Repub primary), James Comey, Rosenstein, Mueller, McCabe (who voted in Repub primary and didn't vote in general) and the other officials and investigators were Republicans and Bush/Trump appointees (except a few of Mueller's most recent prosecutors) Glenn Simpson of Fusion has investigated people of all political stripes and Christopher Steele is a British citizen with no involvement in US politics.

So once they discovered that Fusion GPS 's hiring of Steele was paid by a Clinton Campaign lawyer, that gave them a way to claim the entire probe is merely a partisan Democratic plot that should be discredited.

Democrats didn't reach out to hire Fusion GPS, but after Fusion had conducted several months of research into Trump (before Steele was hired and before Trump won primary) Fusion's Glenn Simpson reached out to contact someone connected to Hillary's campaign to solicit funding for the investigation of Trump to be continued.
