Democrats are really messing up attacking Trump. Trump's policies are well in grained and very popular among working Americans.
The sooner Trump and his policies are separated by having another Republican carry the conservative populist message, the sooner the 7% of Americans that embrace progressive liberalism will find themselves all alone wondering what happened. Progressive liberals have used Trump to gain power, but they have squandered it.
At some level, the Democratic strategists get this, which is why they spent over $50 million in the last election supporting Trump candidates in the primaries to try to buy more time to convince people of their ideology, but it isn't going down well except in the coastal states.
Even as the wealthy Democrats spent a fortune to win the Georgia Senate race, Krystyn Sinema said enough. Expect Joe Manchin to join the chorus soon. Most Americans don't want a government managing their lives and immigrants are especially sensitive to that having fled those governments to come to America.
Long after Trump fades from national politics (and Democrats are trying to make that sooner than later), the new Republican party built around the American worker of all ethnicities is going to move America back towards regulated capitalism and classical liberalism.
So, keep going, collectively Democrats may achieve what Republicans could not... separate Trump from the policies that have reshaped their party.
