Biden crushes sanders in florida and illinois primaries

I'm not aware of any information that suggests Joe Biden "crushed" Bernie Sanders in the Florida and Illinois primaries. In fact, the results of the primaries in those states were quite different.

In the Florida primary on March 17, 2020, Bernie Sanders won with 59.2% of the vote, while Joe Biden received 34.4% of the vote.

In the Illinois primary on March 17, 2020, Joe Biden won with 36.5% of the vote, while Bernie Sanders received 30.5% of the vote.

It's possible that you may be thinking of a different election or a different set of results. If you could provide more information or clarify what you're referring to, I'd be happy to try to help you further.
