They used the money on the election campaign.

All I have seen is that four people worked for the party while being paid by the EU. Nothing like routing money to advertising campaigns or anything that would actually swing an election. And the headlines are all about embezzlement, not election fraud. So this seems like a stretch.

I read that 9 European representatives, plus 12 assistants, plus 4 other members of the party were found guilty as part of a scheme to earn illegally EUR 2.9M for the party.

In my experience, boots on the ground are far more effective at affecting election outcomes than advertising campaigns are.

Go and congratulate Kamala for her win against Trump.

This is just the latest example showing how wrong your take is.

So lets say you have a 6 sided die and you have two options.

1. You win when a 1 is rolled

2. You win when a 1 or a 2 is rolled

Despite both of the situations being less than 50% the 2nd one is still more effective.

(Also your comment implies Trump's campaign doesn't have boots on the ground which obviously isn't true ...)
