Came the day. The United States celebrates the mid-term elections this Tuesday, an appointment that will determine the composition of the two houses of Congress and will condition the last two years of the presidency of Joe Biden. More than 42 million Americans have voted early, according to data from the US Election Project. What is voted? Americans elect the 435 members of the House of Representatives, a third of the Senate (35 of the 100 seats), 36 of the 50 state governors, three governors of US territories, numerous mayoral and local official positions. The Democrats control the House of Representatives and the Senate, but the polls predict a victory for the Republicans who could regain power. The weighted average of polls carried out by the FiveThirtyEight website gives them a 55% chance of winning the upper house and an 84% chance of becoming strong in the lower house. There are three possible scenarios. The Democrats lose the House of Representatives and keep the Senate If the Republicans regain control of the House of Representatives, Kevin McCarthy, who is speculated to replace Nancy Pelosi in the presidency of the lower house if they obtain a majority, already has hinted in recent weeks what could happen, according to the Financial Times. They could use the government’s borrowing limit, commonly known as the “debt ceiling,” to push Republicans’ policy priorities, including major spending cuts. . They would cut future US aid to Ukraine, after Democrats and Republicans have approved tens of billions of dollars in support for the country since the Russian invasion in early February. If Republicans take control of the House, they are likely to disband the committee that investigates the assault on the Capitol. They could also open an investigation of Biden and his son Hunter, whom controversy has haunted for years for his problems with alcohol, drug use and controversial businesses, such as his work for a Ukrainian energy company. Even Biden’s impeachment is not ruled out for a variety of reasons, for example, withdrawal from Afghanistan. Republicans take both houses of Congress from Democrats A “red wave” in Congress would be a landslide victory for Republicans. Despite the polarization in both chambers, Biden has so far scored some bipartisan victories, passing veterans healthcare benefits or investing in manufacturing to curb competition from China, but Republicans would be less likely to allow him more victories as The 2024 presidential election is looming. In the Senate, a Republican majority would make it extraordinarily difficult for Biden to confirm appointments of key officials, foreign ambassadors and judges, even if there is an unexpected vacancy on the supreme court. By contrast, Republican attempts to tighten immigration or gun rights would meet with the president’s veto. Business as usual: Democrats hold majority in House and Senate It’s the least likely scenario or almost unlikely. Still, if it happens, President Biden would face his last two years in office in a similar way to the first two: he will manage to pass progressive laws in the lower house, which will then be vetoed in the upper house by the most conservative Democratic senators. The result of the elections is usually known on the day of the vote, but other times it is so close that days or even weeks can pass. In the United States, there is no central electoral authority and the Secretaries of State of each of the 50 states of the country are responsible for counting the votes. Closer races in Arizona, Pennsylvania, Nevada and Georgia could take until December if no candidate exceeds the 50 percent needed to avoid a runoff.
