Is online voting a security risk?



A person,physically,marking down their vote,in secret,is still the best way. I believe that all people should b compelled,by Law,to vote. In too many cases, a person is elected having gained a percentage of the turnout where less than half of the electorate actually vote.  This can mean a 'winner' getting 25% of the possible number of votes!!

This,to me,means that 75% don't want any of the candidates. If every possible vote was cast,it would give a truer picture.
