Trump slogan "Keep America Great", meaning that the country is only great when Trump is in office? ?

The country was great before the government screwed it up hence the “Make America Great Again” slogan in 2016. The follow up was “Keep America Great” but if Biden fakes his way through this then we’re back to #MAGA

America will just slide back into the pit it was Before Trump. 

Trumps slogan is "Make America Great Again".  It means the country has deteriorated due to poor leadership.  His aim was to provide better leadership, which I believe he has done.  The establishment has finally found a way to defeat the newcomer and resume their control of power.

I don’t know about that

Here's the Trump slogan secret that a lot of people, even some of his supporters, don't realize, but many do!  The "Great" is really "White".

Shhhh, though.  You're not supposed to say it out loud.  

He's not saying it's only great with him but instead it won't be great with Biden.

Sounds like the same thing but I can promise you it means different things.

Trump finally made America great again by losing the election.
