She started that dumb shit a while back, basically trying to point at all the great things a Biden/Harris white house will accomplish to leave the Trump white house in the past. I'm sure the phrase was written by a speech writer. She's way too stupid to have come up with it on her own.
But in her simple mind, she continued to use it over and over and over and over in every God damn speech she gave, when she didn't have the opportunity to read a teleprompter. Her brain just glitched and grabbed on to something she thought was clever in the past, thinking it would make her look smart.
But what's funny is, she's still using that phrase. Too stupid to realize that she is NOW describing the last 3 1/2+ years of the Biden/Harris white house and pointing towards her possible white house. She's about as useful as a poopy flavored lollypop.
