I think the voters, at least some part the voters, would be more reluctant to engage online due to this type of leak. Other than that, they'd continue with their convictions as before.

They should look at the current state of their country, look at the policies of the various parties, and select the party that in their judgement would move the country in the direction think it should move.

I know this is bait, but maybe their reaction should be to go and vote so that the persons who think rape should be OK (as per leaked e-mails btw) don't get to decide?
