In order to pass one's political agenda in the US political system, it is very helpful for a party to control both houses of Congress and the Presidency.
This question asks: Will Republicans win both halves of Congress + Presidency in the US 2020 Election?
This question resolves positively if the US GOP has (a) at least 218 Representatives, (b) at least 50 Senators, and (c) the US Presidency as of 21 January 2021. Candidates who caucus with the GOP will count toward the GOP total regardless of whether they ran as Republicans in the election.
This question has a companion question.
Will Democrats win both halves of Congress + Presidency in the US 2020 Election?
This question and its companion cannot both be true. However they could both be false if there continues to be a divided government in the US or the black swan event that a new party arises that wins the presidency or a house of congress.
A question with direct impact on this one is: Will Trump be reelected president in 2020?
