The U.S. House is showing its support for protesters in Iran.

House Speaker Nancy Pelosi, a Democrat, delivered the oath of office Thursday morning to Tenney in the House chamber in a brief, socially distanced ceremony. Tenney, 59, built a substantial Election Day lead based on votes cast at polling stations, but her advantage shrank to nearly nothing as a record number of mail-in ballots, mostly cast by Democrats, were counted. Important notes related to challenged ballots were lost because they had been written on sticky notes that lost their adhesiveness and fell off. In the end, a judge ruled that Tenney won by 109 votes out of nearly 319,000 votes cast, or a margin of just 0.034%. The victory gives Tenney revenge for her 2018 loss, but she returns to a Washington in which Republicans have lost the White House, the House and the Senate.

(AP Photo/Mike Groll, File)ALBANY, N.Y. – A New York judge ruled Friday that Republican Claudia Tenney defeated U.S. Rep. Anthony Brindisi by 109 votes in the nation's last undecided congressional race. He rejected an argument by Brindisi's lawyers that certification of the election results should be delayed until an appeals court had a chance to review the case. DelConte said Brindisi can still challenge the election in the House and potentially unseat Tenney. The U.S. House can unseat a member who is “not truly the lawful winner of an election,” the judge wrote.

Democrats boast an ever-expanding target list that includes a half-dozen Republican seats in Texas plus others outside Atlanta, Cincinnati, Los Angeles and Phoenix. The tale of two districts 1,600 miles apart spotlights that many pivotal House races hinge on suburban voters. We're still on offense, said Rep. Cheri Bustos, D-Ill., who leads House Democrats' campaign organization. Since January 2019, all 29 Democrats in House districts Trump carried in 2016 have banked more money than their GOP challengers, usually by multiples. The same is true for all but two of the 24 other Democrats in seats Republicans said they'd pursue aggressively this year.
