The Hill has identified these four Senate races that could lead to Democrats winning a Senate Majority:

Democrats are racing to broaden their path to the Senate majority in November, while Republicans are spending heavily in an effort to hold their control over the chamber.

With 200 days to go until Election Day, the Democrats’ path to a Senate majority currently hinges on four states: Arizona, Colorado, Maine and North Carolina, where Republican incumbents are fighting off challenges from well-funded Democratic opponents.

Democrats need to flip three or four seats, depending on which party wins the White House in November, to take control of the Senate. But one of their incumbents up for reelection this year, Sen. Doug Jones (D-Ala.), is in serious political jeopardy, meaning that Democrats will likely have to take at least four Republican-held seats — and hold back GOP challenges in nearly a dozen other states — to win a majority.

Also weighing over the battle for control of the Senate are the presidential race and the ongoing coronavirus pandemic, which has upended the election cycle and now looms as perhaps the biggest variable in 2020.

“A presidential campaign always has the longest and most powerful coattails,” former Rep. Steve Israel (D-N.Y.) said. “If President Trump is perceived to be doing well, it will retain the Senate Republican majority. If in October he’s underwater, then the Democrats could take the Senate.”

To be clear, the article just focuses on these four races. There are more races that Democrats are also targeting but I’d recommend you give the article a read and donate and get involved with these Democrats Senate campaigns:

Mark Kelly (D. AZ)

John Hickenlooper (D. CO)

Sara Gideon (D. ME)
