They are concentrating on taking back five key states lost by less than three percentage points in 2020.

Those are the three rust belt states of Pennsylvania, Michigan and Wisconsin, plus Georgia and Arizona.

Mr Trump is actively backing candidates for local offices in those states, which could ultimately help him in a presidential election.

New polling conducted by Mr Trump’s former pollster Tony Fabrizio showed him currently leading Mr Biden in all five states.

Mr Trump had leads of 12 points in Michigan, 10 in Wisconsin, eight in Arizona, six in Pennsylvania, and three in Georgia.

Mr Fabrizio said: “This new data clearly shows that, today, the voters in these five key states would be happy to return Trump to the White House and send Biden packing.”

He added: “Poll after poll clearly demonstrates that former President Donald Trump is still the 800-pound gorilla in the Republican party.”

The polling showed Mr Trump leading Mr Biden on a host of issues including who was best to handle the economy.

Meanwhile, Democrat polling showed voters are now confused about what the party stands for.

In the wake of Democrats losing the governorship of Virginia in an election this month, the party conducted focus groups in the state.

They found that Democrat voters “could not say what they [Democrat politicians] are doing in Washington, besides fighting.”
