Indeed, however one must differentiate between "voter fraud", which has proven insignificant time and again, and vote tampering carried out by election workers and associated officials. Internet connections make such tampering easy, though perhaps not so easy to cover up. Tampering can include allowing partisan hacks to stand around entrances to polling places intimidating voters, gerrymandering, deliberately restricting the number of voting machines available in certain areas, and demanding ID where voter names, addresses, and phone numbers are already well established and affirmed with a compared signature. Mail in ballots have largely begun to eliminate such nonsense, thank goodness.
