I don't know about bigger stink… the presidential election attracts more national attention.. but you're not wrong.. should all be investigated..
On a side note, there's already been evidence that suggests the fraud was more significant in the presidential election as well, with republicans winning in districts where Trump lost and saying "wtf? I only won because of all the trump supporters voting for me, how did Trump lose my district"
Some hacks/adjudication may have only "fixed" that top selection, without altering down the ballot.
