Help please, I'm stuck again. What is 8d? Writing American volume with a true change of heart therein (10) I have ??t?r?????.

Also, is 19a Constant failure as person could make you more careful (6) closer?

And would someone like to explain why 23d Split in political group can be a blow (4) is left?

Thanks for the help.

I suppose that "c" is for "constant" and "loser" is failure as a person.
Left of a political party they are a bit of a split, and "left" as in left hook(?)

8d american volume = LITER, a = A, true change of heart therein = TURE

23d triple definition

split = departed = left
political group = left (as opposed to right)
blow = left (in boxing))
