Former vice president Al (4)
I believe the answer is:
gore
'former vice president al' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for gore that I've seen before include "Result of bleeding" , "stuff from part of Kensington" , "Pierce or wound with a horn or tusk" , "piece of material" , "Showing guts" .)
