A recent NBC News poll indicates that 49% of registered voters prefer Democratic control of both chambers of the U.S. Congress, while 44% favor Republican control. This shift in voter sentiment, coupled with President Donald Trump’s average approval rating of 38% according to The New York Times, suggests a potential realignment of power in the upcoming midterm elections.
Why Congressional Oversight Matters for the Executive Branch
If Democrats win control of Congress, the primary consequence will be an intensified level of oversight regarding the Trump administration. According to Hilmar Mjelde, a professor of political science at Høgskulen på Vestlandet, legislative bodies are constitutionally obligated to monitor the executive branch, regardless of party affiliation. Mjelde notes that when a president’s own party holds the majority, that oversight often wanes, effectively turning the legislature into “obedient subjects” rather than a check on executive power.

Could a Third Impeachment Occur?
The possibility of a third impeachment remains a topic of political discussion. Mjelde suggests that while the “ghost of impeachment” will continue to loom over the Trump presidency, the practical impact may be minimal. Under the U.S. Constitution, the House of Representatives holds the power to impeach with a simple majority, but conviction and removal from office require a two-thirds majority in the Senate.
Historically, impeachment has been a rare mechanism. Trump is the only president to be impeached twice: first in 2019 over allegations of pressuring Ukraine to investigate Joe Biden, and again in 2021 following the January 6th Capitol riot. He was acquitted by the Senate in both proceedings. Mjelde estimates there is a greater than 50% chance of a third impeachment attempt, though he notes that without broad, bipartisan support, a conviction remains unlikely.
The Shift Toward Executive Independence
President Trump has increasingly operated as a “freestanding actor” within the U.S. political system, according to Mjelde. By frequently utilizing executive orders to bypass Congress, the administration has asserted authority over domains traditionally managed by the legislative branch, such as the allocation of public funds. This strategy has allowed the executive branch to maintain momentum even when facing resistance from Capitol Hill.
Did you know?
The current balance of power is narrow: Republicans hold 218 seats in the House and 53 in the Senate, while Democrats hold 212 in the House and 47 in the Senate (including two independents). With four seats currently vacant in the House, even small shifts in voter turnout could decide control of the chamber.
