Drink like this with Democrat leader in Alaska (4)
I believe the answer is:
soda
'drink' is the definition.
(soda is a kind of drink)
'like this with democrat leader in alaska' is the wordplay.
'like this' becomes 'so' ('like so').
'with' is a charade indicator (letters next to each other).
'democrat' becomes 'd'.
'leader in' says to take the initial letters.
The first letter of 'alaska' is 'a'.
'so'+'d'+'a'='SODA'
(Other definitions for soda that I've seen before include "Drink containing carbonated water and sometimes flavouring" , "kind of water" , "Splash served with some spirits" , "Whisky mixer" , "In the US, a sweet fizzy drink" .)
