With just two days left before the US midterm elections, leaders from both parties are making a final push to win over voters, as the rising cost of living and the economic fallout of the US-Israel war on Iran dominate the campaign. Democrats continue to lead Republicans in national polls, but several closely contested Senate races could determine which party controls Congress. President Donald Trump is campaigning for Republican candidates, while Democrats are seeking to turn voter dissatisfaction over the economy into electoral gains. More than 51 million Americans have already cast their ballots, although early voting figures do not indicate which party is ahead. Here is the latest on the US midterms as the campaign enters its final stretch: Democrats continue to hold a lead over Republicans in national polling, according to the latest RealClearPolling average. The party is ahead by 51.5% to 43.1%. A THP/MM survey conducted on October 28 and 29 put Democrats ahead by 54% to 41%. An Emerson College poll conducted between October 24 and 26 also showed a 10-point Democratic advantage. Democrats have opened a seven-point lead over Republicans in the race for control of Congress, with voters expressing growing dissatisfaction with President Donald Trump and his handling of the economy, according to a new NBC News poll. The survey, conducted among registered voters between October 28 and 30, found that 52% preferred a Democratic-controlled Congress, compared with 45% who wanted Republicans to retain control. However, the national picture does not necessarily reflect the state of individual Senate contests. In Kansas, a Washington Post-Schar School poll released on Friday showed Democratic candidate Adam Hamilton leading Republican Senator Roger Marshall by 52% to 43%. An Emerson College survey indicated a narrower contest, with Hamilton ahead by 50% to 47%. The outcome of several closely fought races could prove decisive in determining control of the Senate. Donald Trump returned to campaigning for the day in Dubuque, Iowa, where he headlined the first of two campaign events slated for him today. Trump’s appearance was initially canceled, along with another event planned for Salina, Kansas, raising some concerns that the president was abdicating his plans to campaign up until the midterm elections. But the president reversed course, rescheduling both events, in addition to a long slate of remote tele-rallies planned for candidates across the country. Speaking to one of his final campaign crowds of the midterms in Iowa, Donald Trump praised congresswoman Ashley Hinson, the state’s Republican Senate nominee, for losing weight. “I knew Ashley for a long time, and she was a little bit heavier. She was,” Trump said. After being briefly interrupted by protesters in the crowd, he concluded: “She put herself in shape, she’s in perfect shape.” The Michigan Senate race saw a fresh development on Sunday after Representative Haley Stevens, who lost the Democratic primary to Abdul El-Sayed, endorsed Republican candidate Mike Rogers.
