The voting process has begun in the midterm congressional elections in a number of eastern US states, with the opening of polling stations in New York, New Jersey, and Virginia. Voters choose all 435 members of the House of Representatives and thirty-five of the 100 members of the Senate. It is enough for Democrats to increase their representation in the House of Representatives by only four seats compared to the current two hundred and fourteen seats to reach the threshold of two hundred and eighteen seats necessary for a majority. In the Senate, Republicans cannot lose more than three seats to maintain control of it. Republicans are defending 22 of the 35 seats offered, while Democrats are defending 13 seats, according to an Al Jazeera report published on October 26. Fifty seats are enough for Republicans to maintain a majority, as the US Vice President decides the tie with his vote, which explains the three-loss threshold mentioned above. If Democrats control Congress, they will be able to obstruct US President Donald Trump's legislative agenda, conduct investigations into his administration, and restrict government spending. Control of the Senate will also enable them to block the appointment of nominees proposed by the president to fill government positions. The midterm elections in the United States on November 3 will determine the balance of power in Congress for the next two years, and will be one of the major political events in the second presidential term of US President Donald Trump in light of economic difficulties and the deteriorating international situation. A New York Times report published on October 22 talked about American-Israeli plans to strike Iran after the vote [2]. The last polling stations in the Western Aleutian Islands close, with voting ending at 01:00 Eastern time (09:00 Moscow time on November 4), and sources reported that approximately fifty million voters out of two hundred and ten million registered voters have voted in advance.
