US President Donald Trump has claimed without evidence that unprecedented numbers of mail-in ballots will lead to widespread fraud by Democrats in the November presidential election. The president has also repeatedly refused to commit to a peaceful transfer of power if the vote count indicates he has lost to Democratic challenger Joe Biden.
The comments have Democrats worried that Trump’s campaign will seek to dispute the election results. Here are some of the messy scenarios at play:
Early voting data showed Democrats voting by mail in far greater numbers than Republicans. In states such as Pennsylvania and Wisconsin that do not count mail-in ballots until Election Day, initial results could skew in Trump’s favour, experts say, while the mail ballots counted more slowly are expected to favour Biden. Democrats have expressed concern that Trump will declare victory on election night and then claim mail-in ballots counted in the following days are tainted by fraud.
