 More than 20 million people across the US have already cast their ballots for the crucial midterm elections slated to be held on Tuesday.

According to Catalist, a data company that works to compile counts of ballots cast before Election Day, the votes were coming in from seven critical states -- Arizona, Florida, Nevada, Georgia, Texas, Tennesse, Montana, CNN reported on Monday. 

In Arizona, Representatives Kyrsten Sinema (Democrat) and Martha McSally (Republican) were vying to become the first female senator to represent the Grand Canyon state.

According to an NBC/Marist poll released last week, Sinema topped McSally by 6 points. 

So far, 34 per cent of votes have been cast by Democrats and 43 per cent by Republicans, while independent voters accounted for 18 per cent, with another 8 per cent recorded as "unknown".

In Florida, the Senate race is between Democratic incumbent Senator Bill Nelson and Governor Rick Scott, CNN reported.

Over 3 million votes have been cast ahead of Tuesday`s midterms so far, the Catalist data showed, surpassing what was reported at this point in the last polls held in 2014.

Examining the early votes, 40 per cent were cast by Democrats and 42 per cent by Republicans. 

CNN`s most recent polling showed Nelson was just a two-point lead over Scott.
