Busses with a Lula insignia on it, which is an electoral crime.
Just as bad as storming the capitol!
However, it is an electoral crime to do things like stamp public transport vehicles with a party insignia to "remind" candidates who provides for them. As such, it's not at all surprising that the busses were grounded.
Also it's a good thing people were afforded more time to vote in case their buses weren't running.
It would be sad for a Bolsonaro voter to not be counted because some cheeky rapscallion stickered a bus.
Thank goodness both candidates sought extension and it was granted.
