The battle for the US presidency looks set to go all the way down to the wire. Former Vice President Joe Biden is in the lead but not a comfortable lead just yet. President Donald Trump and Biden are neck and neck in at least 6-7 swing states and those are the states which are going to count this time around. So if Joe Biden has a lead of around 220 electoral votes, Trump has a lead in about 213. So Joe Biden needs about 50 more electoral votes and Trump needs 57. Parikshit Luthra has a quick update.
