With Election Day just around the corner, every race is heating up and starting to spring towards the finish line. Republicans and Democrats are fighting tooth and nail for Senate seats, with Republicans looking to keep the Senate and Democrats trying to flip it and gain control of both Houses. Here is a list of the most competitive races and ones that will determine who takes the Senate. 

ARIZONA: Martha McSally (R) vs. Mark Kelly (D)

Former fighter pilot and incumbent Martha McSally is facing astronaut Mark Kelly in this race that will decide if the state has two Democratic senators for the first time in decades. McSally was appointed to the late-John McCain’s seat in 2018 and is running to be able to finish the term. Polls have this race neck and neck, with Kelly ahead by a slight margin. Money is pouring into this election and is one of the most-expensive elections this cycle. This race will be key to keeping the majority in the Senate and is targeted by Republicans and Democrats as a top race.

COLORADO: Cory Gardner (R) vs. John Hickenlooper (D)

Incumbent Cory Gardner is facing former Colorado Governor John Hickenlooper in this heated battleground race. A poll released on last Thursday shows Hickenlooper with a five point lead over Gardner, his narrowest lead since the race began. Out of state money has been a huge factor of this campaign with dark money and non-profits spending $27 million alone on just ads. With Gardner being considered one of the most vulnerable Republicans this election and will be a huge factor in deciding if the GOP will keep the Senate. 

IOWA: Joni Ernst (R) vs. Theresa Greenfield (D)

Elected in 2014, Joni Ersnt is fighting to keep her seat in the Senate in this neck and neck race against Theresa Greenfield. Greenfield was the former 2018 Democratic candidate for Iowa’s Third Congressional district but has no political experience other than that. Polls fluctuate between the leader but Real Clear Politics has Greenfield up by 0.3%. Ernst has faced backlash over the past few weeks over Iowa’s COVID-19 cases and is working with the Trump team in order to keep the state red in November. 

MAINE: Susan Collins (R) vs. Sara Gideon (D)

Long-serving Republican Senator Susan Collins is facing her toughest battle yet against Sara Gideon, who is the former Speaker of the Maine House of Representatives. Real Clear Politics (RCP) has Gideon up 4.5 points on average. Collins, who has tried to distance herself from President Trump over the past few weeks is looking to maintain her moderate-Republican stance in the state that voted for Hillary Clinton by a little over two points in 2016.

MONTANA: Steve Daines (R) vs. Steve Bullock (D)

Serving the state of Montana in the Senate since 2014, Daines is looking to Steve Bullock, who is currently serving as Governor of Montana. Polls show Daines having a close, yet steady lead over Bullock according to FiveThirtyEight. Fundraising for this race has already broken records formerly held in the state and out of state money and dark money has been pouring in. Cook Political Report recently moved this race into the “toss-up” category due to the competitiveness of the polling and fundraising this race has drawn.  

NORTH CAROLINA: Thom Tillis (R) vs. Cal Cunningham (D)

Current Senator Thom Tillis is looking to keep his seat in the Senate against former State Senator, Cal Cunningham. Polls have this race tight, with RCP showing Cunningham up 3.3 points as of September 13th. This battleground state will be another state that is key to keeping the GOP majority in the Senate and is also targeted heavily by both the RNC and DNC. According to the quarter two FEC reports, Cunningham has outraised Tillis by a little less than 800,000 and Tillis has more cash on hand at 6.82 million.
