The two lead issues of the economy and illegal migration were issues where President Trump and the Republicans were on the more popular side of the argument. I have not commented on their election during its progress but am not surprised by the likely results.
The mistakes of western governments over Covid lockdown reinforced by the big errors of the Fed, the Bank of England and the European Central Bank over inflation, money and interest rates were bound to lead to bad election results for them. We have seen the governments of France, Italy and the U.K. fall, to be followed by the US and probably Germany next year. Electors hold governments responsible for inflation as they cannot throw Central Bankers out when they get it hopelessly wrong.
