This election marked the first time in history an electoral deadlock in the Assembly occurred, where the PNM and the PDP won an equal number seats of 6-6, triggering a constitutional crisis with both political parties and Prime Minister Keith Rowley seeking senior counsel advice on the way forward.

On 1 August 2021, Emancipation Day, a new political party called the Innovative Democratic Alliance (IDA) was launched[11] by former PNM member Denise Tsoiafatt-Angus who ran unsuccessfully as an independent in the January 2021 elections for the Scarborough/Calder Hall seat.

With the stakes even higher than the January elections, the PDP campaigned on being an indigenous Tobagonian party proposing a change of the current order to attain independent self-government and equality of status to Trinidad within the Republic.

[15] During the campaign trail past issues were rehashed; the incomplete Main Ridge Forest zip line project and the leadership decisions of Tracy Davidson-Celestine surrounding the resignation of Kelvin Charles as Chief Secretary and the expulsion from the PNM Tobago Council of the then-Presiding Officer (now IDA founder) and Political Leader, Dr. Denise Tsoiafatt Angus.

[19][20] Also, the leadership role and past decision making of controversial political leader Watson Duke as Public Services Association President were highlighted.

[22] Meanwhile, in Trinidad, the UNC accused the Prime Minister Dr. Keith Rowley, himself a Tobagonian and the political leader of the PNM, for failing to declare to the Integrity Commission his interest in the Inez Gate Private Development at Shirvan Road, Mount Pleasant.

[23] This charge was vigorously defended and dismissed by Dr. Rowley in a media conference accusing the UNC of intervening and assisting the PDP in the final week of the election campaign.
