Facts such as you have stated do not matter to the liberals.
The liberals pushed their narrative, which was that Bush ignored the suffering caused by Katrina. The message was eagerly reinforced by the lapdogs in the media, who were eager to do the bidding of the liberals. Useful idiots such as rapper Kanye West reinforced the message that Katrina was a racist event.
I remember that Bush signed the disaster order even before Katrina hit. He took what actions he legally could beforehand, as we knew this was a huge storm.
I have barely heard about the Minnesota floods in the MSM. I think we see that the media will just ignore things which they don’t want to talk about.
Remember the historic Nashville floods of 2010? Didn’t think so. The media almost completely ignored that one too. I have yet to hear Obama speak of that event.
You won't. White? Obama hates them. Christians? Obama hates them. Conservatives? Obama hates them. No aid for you.
