Much of our system is geared towards fraud - on site voter registration, no ID voting, drive-up voting, early voting, multiple forms of ballets, electronic voting.
While the Feds should NOT be involved in organizing or standardizing elections (that could allow the biggest fraud of all), states need to tighten up requirements for registration and voting - and who counts the votes.
It is set up for Fraud by design. Those who cast votes decide nothing, those who count votes decide everything. Sad really
