Everyone needs to vote, and if you're registered in a swing state, it's that much more vital. Let's make sure Joe Biden has a strong Senate behind him when he takes the White House!
Democrats hoping to control the Senate need to net four seats in November (or three if they win the White House since the vice president has a tiebreaking vote). Their top targets are Republican incumbents in Colorado, Arizona and Maine. Close behind are the incumbents in North Carolina and, increasingly, Iowa.
