With victories in 7 states, Biden closes in on nomination

Joe Biden is on the cusp of formally securing the Democratic presidential nomination after winning hundreds more delegates in primary contests Tuesday that tested the nation's ability to run elections while balancing a pandemic and sweeping social unrest. Biden could lock down the nomination within the next week as West Virginia and Georgia hold primaries. On Tuesday, voters across America were forced to navigate curfews, health concerns and National Guard troops — waiting in line hours after polls closed in some cases — after election officials dramatically reduced the number of in-person voting sites to minimize the spread of the coronavirus outbreak.
