The variation in Electoral College vote tally is due to the difference in projection by different news outlets
It is understandable should one gets confused seeing different tallies at the top of the live coverage of the US presidential election from various news sites.
The variation in Electoral College vote tally is due to the difference in projection by different news outlets, reports the BBC.
Some news sites have projected wins in Arizona for Joe Biden - meaning an extra 11 Electoral College votes, and Wisconsin - which would mean 10 Electoral College votes.
Organisations such as polling firm Edison Research does the field work for the exit polls and works with US networks in the National Election Pool.
In Wisconsin, 99% of the votes have been counted, with the candidates neck and neck.
85% of votes have been counted in Arizona, and Biden is leading with 51% of the votes, with Trump on 48%.
