You do know she’s running right?
The earliest she could run is 2024. There’s no way she’d run in 2020 against Trump. He’d destroy her. She has to wait until there is an establishment Republican candidate...like a Mitt Romney in order to run. Someone who would defer to her as another establishment candidate.
Trump wouldn’t pull any punches and she knows it. She just has to stay in the public eye so she isn’t upstaged by the plethora of Democratic women running now or AOC, when she becomes old enough for the job.
