"However, the Biden administration will find it more difficult to push financial aid programmes to Kyiv through Congress, and the position of U.S. critics of unlimited aid to Ukraine will markedly strengthen."

    Pushkov, who had sanctions placed upon him by the European Union in March for voting to support Moscow's Ukraine policy, said he thought there was a chance that Republicans might target what he called Biden's "wasteful" Ukraine spending in the run-up to 2024 to try to hurt the Democrats' ratings.

    But a report drawn up by the Moscow-based Institute for International Studies, which shares its research with the Russian Foreign Ministry and other state bodies, concluded that the mood of what it called the U.S. establishment and the electorate meant the elections were unlikely to bring about major changes to Washington's Ukraine policy.

    Ukraine has rarely come up as a key voter concern, with those polled ahead of the election citing mostly worries on domestic issues like inflation, crime and abortion.

'CRITICAL JUNCTURE'

    Russian ultra-nationalist circles were more certain that the midterms - in which Republicans are forecast to win control of the House of Representatives and possibly the Senate - would be positive for their long-term interests.

    Tsargrad, an online news portal and TV station funded by sanctioned Russian ultra-nationalist tycoon Konstantin Malofeev, predicted the elections would ultimately be America's undoing.

    "At a critical juncture in world history, this election could have a major impact on the geopolitical environment, and Ukraine in particular," it wrote.

    "But it could also be the detonator of domestic centrifugal processes that could end the United States as we know it today," it said, talking of the theoretical possibility of civil war due to political polarisation and distrust of election outcomes.

    If such a dramatic scenario unfolded, Washington, Tsargrad predicted, would not have the capacity to keep prosecuting its Ukraine policy.

    In a column for the state-run RIA news agency, columnist Pyotr Akopov also forecast that Russia would be the real winner of the U.S. midterms because the vote would deepen political divisions ahead of the 2024 presidential election which he predicted would be disputed.

    "Even if it survives as a single state, the United States will change dramatically and its global position will weaken under any circumstances," Akopov opined.

    "Confrontation with China will require the mobilisation of all of the country's global resources - and attention to Europe will inevitably weaken," he said. "Without a strong and united (United) States the West will not be able to maintain control over western Russian lands for long."
