The Senate has been in play for at least nine months, but Democratic chances of winning control of the chamber have improved significantly in the last few weeks.
As Joe Biden has grown a significant lead over President Donald Trump in the race for the White House, the Senate battleground has improved for Democrats down the ballot. Some states, such as Colorado, Arizona, Maine, and North Carolina, have been competitive for the entire cycle. But previously lower-tier contests in Iowa, Montana, and Georgia are now neck-and-neck races. And Kansas, Texas, and even Alaska and South Carolina can’t be considered solid for Republicans anymore. That gives Democrats more than one legitimate path.
