Coercion by threat is only part of the problem; the bigger risk is buying votes. The threat of prosecution can be dodged by taking offers "off-grid", farming it out to people on the street who have no official connection to the campaign. And to those who are cynical about politics and/or struggling to make ends meet, getting paid for your vote would be mighty tempting. I do believe secure and secret electronic voting is possible, but I have little faith in the current government-industrial complex to give a shit about getting it right. At least paper voting works, and has a lot of eyeballs on it to prevent fraud.
