What should you be primarily worried about? It's like serving your e-commerce website over HTTP because there have been very few security breaches. Why not get a certificate and use HTTPS? It's a massive improvement in security for a very small cost.

Not analogous,because attacks relying on coordinating large numbers of people (with a high rate of detection) simply doesn't scale. We should be worried about electronic attacks on voting infrastructure, political attacks on districts, political attacks on the registration process etc.
