In the past week or so, Biden has visited North Carolina and Pennsylvania and, so far this week, we know he will be heading to Georgia. At the beginning of this cycle the state was seen as a reach for Biden. Now it very much could go either way.
In the coming days, Biden's vice presidential nominee, California Sen. Kamala Harris, is going to Nevada and, as NPR has confirmed, Texas, a state that continues to be close. Former President Barack Obama is going back to Florida, where he also was Saturday.
Trump, on the other hand, is headed to Pennsylvania, Michigan, Wisconsin and Nebraska (yes, Nebraska). Biden has been leading in the Omaha-area congressional district and is close in another bordering district. (Nebraska allocates its electoral votes by a combination of congressional district and statewide vote.)
Vice President Pence is headed to Minnesota and North Carolina, as well as South Carolina, where Republican Sen. Lindsey Graham is in a tough reelection fight.
