The push to e-voting actually surprises me - if it was just one country, I'd write it off as just one of those things, but the fact that it keeps happening in country after country. Generally speaking, most human behaviour can be explained by assuming that people value status and power above all other things. So you can expect those in power to try to keep that power.
But e-voting surely does the reverse: it throws open the playing field, putting power up for grabs to whoever can hack the system, with no way to predict who that will end up being. So why do those currently in power want that to happen? (Not a rhetorical question: I'm actually curious about the answer.)
