No, she's just keeping her brand out there and getting the attention she craves.
She still has fans who will watch the movie, but the party gave her every advantage in 2016 and she couldn't pull it off.
Nobody thinks she'd do better in 2020.
Running does not mean winning the nomination or the general election. Running means running and putting her brand out there as you say. Why put the brand out unless you want to make the sale? Doesn’t mean you will, you just want to! Her ego demands that she run & keep the meme going she was robbed in 2016.
If she’s breathing she’s running!
