How many more votes would the party in second place at the last election have needed in order to have won instead?

Is there a mechanism by which the election could be run again (before the winners of the election have a chance to prevent this)?

Or it's an argument that a voting system should have both hand-counting and digital counting, because rigging both counts is at least twice as difficult as rigging one.

5.8% of the total votes [1] but winning the election is just part of the game. This time around the winning party isn't in power because the runner ups formed a coalition.

> Is there a mechanism by which the election could be run again (before the winners of the election have a chance to prevent this)?

Several - the previous government would still be in power for some time to react, the president has to sign off on the winners, the defense police could intervene, and then there are the courts. None of these entities depend on the newly elected government.

> both hand-counting and digital counting

That would certainly be more secure, but like all security it would be a trade off.

It's a multiple party proportional representation system so who "wins" doesn't really matter that much.

I'm not an electoral law expert, but complaints about election process go to National Electoral Committee, which can have its decision contested in Supreme Court.

The e-voting over here is actual e-voting - the vote is purely digital and done remotely. Not in any way related to the digital vote counting machines used in the US.

Obviously by "wins" I meant "becomes the (biggest party in a coalition) government", not "gains the most first preference votes" or some other strawman interpretation. And yes, I admit that it is hard to calculate the minimum number of extra votes that would need to be added to change which party leads the government, but I do think that a good proportional voting system should allow that number to be determined at least to a reasonable approximation.

> I'm not an electoral law expert, but complaints about election process go to National Electoral Committee, which can have its decision contested in Supreme Court.

I wonder how long that process would take in practice, and whether the Supreme Court would decide it had the power to invalidate an election. In particular, what sort of evidence would be required to satisfy the court that it had to demand that remedy? I imagine that "The opinion polls were wrong by 6%" might not be enough, and the political biases of the judges themselves might well be significant in such a situation.

Yes, the fact that the voting can be done remotely is another problem, since someone can be bribed or coerced into voting a certain way. I believe the mitigation for this is that the voter can supersede their online vote with an in-person vote, but an attacker could quite cheaply work around this by having tracking software on the victim's phone, and henchmen outside the polling stations.

Unless the party rigging the counts is the one currently in power. Which in my opinion is the main risk, however minuscule and unrealistic.
