WASHINGTON - NPR reported that Democrats will hold "significant majorities" in both chambers of the next Congress and are planning for the term ahead. In the same report, the network said President Trump signaled his own plans by promoting Stephen Miller as his new Chief of Staff. NPR covered both developments in its weekly politics roundup, Week in politics: Democrats plan for the next Congress, Trump's new Chief of Staff.

The Guardian described Tuesday's midterm elections as a "monumental return to power" for Democrats, giving them new leverage over Trump. Reporter Chris Stein wrote that the period ahead is expected to bring tough campaigns of investigating and lawmaking. The Guardian noted that Democrats had spent almost two years criticizing Trump over costs, chaos and corruption before the vote. Its headline, Healthcare, tariffs - but not Trump impeachment: Democrats chart next two years of power, indicated that the party's focus would be healthcare and tariffs rather than impeachment of Trump.

An opinion piece in The Hill, written by opinion contributors Douglas E. Schoen and Carly Cooperman, offered a different explanation for the result. The authors argued that the Democratic landslide reflected frustration with Trump and Republicans more than a Democratic vision and agenda. The piece is labeled opinion and is not a news report. It appeared as Democrats won big - why and what comes next may matter more.

The sources differ on why Democrats won. The Guardian tied the outcome to the party's earlier criticism of Trump, while The Hill's contributors attributed the landslide mainly to voter frustration with Trump and Republicans. NPR's summary did not address the cause of the results.
