Actually, Trump did move to the middle in a lot of hugely important ways. Trump shrank the gap between rich and poor, which should satisfy leftists, but they refuse to acknowledge it. Trump did increase the wealth of the African American electorate, which is why he increased African American and Hispanic support for the Republican Party. Trump actually got Germany to increase defence spending, and the U.S. military under Trump did a lot of training with the Ukrainians, which should satisfy traditional real politik politicians in the center of both parties and is a major reason Ukraine is doing as well as it is. Biden is thankfully continuing with Trump’s anti-CCP policies.
