WASHINGTON: Before Saturday, Biden had at least 253 electoral votes, meaning the win in the Keystone State put him at 273. He later claimed victory in Nevada, boosting his total to 279. Some US media outlets have also declared him the winner in Arizona, which would put him at 290. Biden has captured 24 states including his home state Delaware and big prizes California and New York, as well as the US capital. The former vice president has flipped four states won by Trump in 2016 -- Michigan, Pennsylvania, Wisconsin and, according to two news organizations, Arizona. US media outlets have projected wins for the Republican incumbent in 23 states including big prizes Florida and Texas, as well as Indiana, Kentucky, Missouri and Ohio -- all states he won in 2016. As it stands, there are three states still left uncalled -- Alaska, Georgia and North Carolina. But Biden's lead is now insurmountable.

In the case of Arizona, Fox News and the Associated Press have already called the race in Biden's favor. But other networks including CNN and NBC News have held back thus far, as the race remains tight. Nebraska split its electoral votes between the two candidates -- four for Trump and one for Biden. Maine was won by Biden, but he seized only three of the four electoral votes on offer, with the last allocated to Trump.
