Quick Summary

With just one week until the midterm elections, control of both houses of Congress is up for grabs as voters consider their support for President Donald Trump's administration and the current Republican majorities in the House and Senate. In the House, Speaker Mike Johnson holds a narrow 218-214 edge over Democrats, with two vacancies; Democrats need to win at least three seats to gain control. Meanwhile, in the Senate, Republicans are defending 22 of 35 contested seats compared to 13 for Democrats, but the political landscape remains competitive across many states.

Democrats are aiming to make gains by targeting traditionally Republican districts. The key races will determine whether Republicans can preserve their majority or if Democrats can secure enough seats for control, particularly focusing on crucial seats in historically red areas. The outcome could impact the balance of power between President Donald Trump's administration and Congress.

Why this leaning score
This article does not take a side on a contested political question, so it has no leaning score. That is an answer rather than a gap: a match report or a rescue can be warmly or critically written without being left or right, and scoring it anyway is how approval of a subject gets recorded as a political position.
