She's running in a primary challenge against an established Democrat who has been active in Maryland politics since the 1960s and has never lost an election.
On top of that, polling suggests that a majority of Americans, including just under 50% of Democrats, opposed clemency for Manning.
This is not going to end well. If she's serious about a career as an elected official, this is not the right way to go about it. I suspect she does not expect to win and this is really an attempt to gain national recognition as an activist.
