The Republicans are using that financial advantage to buy advertising.
More than $1bn worth of political ads were broadcast to US voters in September, according to research firm AdImpact, external. Republicans spent $200m more than the Democrats and outspent them in nearly all of the Senate races classed as toss-ups.
Trump will be hoping this late messaging blitz can help convince Republicans to get out and vote in November, boosting turnout and limiting the damage done to him and his party.
Whatever the result, attention will quickly turn to the next presidential election in 2028. Trump’s unpopularity has dominated the midterms, but with him constitutionally unable to run for a third term the focus will shift to what the Democrats stand for, not just what they stand against.
