Demoralised, like the Tories with Theresa gone? (8)
I believe the answer is:
dismayed
'demoralised' is the definition.
('dismay' can be a synonym of 'demoralize')
I don't understand the remainder of the clue.
(Other definitions for dismayed that I've seen before include "Alarmed, discouraged" , "Struck with fear or dread" , "Demoralised" , "Dispirited" , "Cast down" .)
