American senators have floated the possibility of November’s presidential election being carried out purely by mail votes as the impacts of coronavirus on the campaign calendar begin to enter the spotlight.
Some have suggested that if the outbreak is still on-going later this year there could be no in-person voting at polling stations in what would be a remarkable break with historical precedent.
Other ideas such as electronic voting done remotely or increased use of absentee ballots so the elderly who are most vulnerable to the virus could stay at home have also been raised as possibilities.
There has even been loose talk from Democrats that Donald Trump could push back the election date - despite the fact that the US president has made no public indication that he could do so.
The discussions in Washington DC reflect the degree to which the Covid-19 pandemic has thrown the well-established election year calendar into disarray.
