I don't think I could ask him to step in now.
I vividly remember how racist and white supremacist Republicans were to President Obama and First Lady Obama. And his kids.
Now that the Republican masks are off with Republicans having gone full white supremacists/NAZI/fascists ideologues I would not ask Obama et al to risk it for a nation unwilling to go on general strike to stop this hot garbage administration.
The Obama family served the USA. It is our turn to show the Obama family what we can do.
