Lula has been mired in corruption charges out the wazoo. Now, it turns out that at least some of them were a result of a corrupt, right-wing judiciary colluding against him, so his initial conviction was rightly overturned. But he was facing a lot of charges, and they were not necessarily all made up. Regardless, they were all swept away, just like that, meaning he has neither been found guilty or innocent of most of the charges of corruption against him.

Among all the people in as populous a country as Brazil, you'd think you'd be able to find a better candidate than an unpopular geriatric, who, rightly so or not, has had an incredulous amount of accusations of corruption against him.

But even if Lula was the second-worst possible candidate in all of Brazil, he is still many, many orders of magnitude better than the candidate he ultimately ran and won against. There's no comparison.

Half of the Supreme court is involved in a corruption scandal, while he is papering over the problem; Half of the Congress is involved on that same scandal and some half in another large scandal, and he didn't direct the police to investigate (he and the Supreme Court are the only ones that can); We have a new law mandating that common crimes from politicians can only be judge by a court that has no judge, and he was one of the main creators of it... The list goes on and on.
