'slogan' is the definition.
(I've seen this before)

'take care of controversy over democrat's' is the wordplay.
'take care of' becomes 'watch' (I can't explain this - if you can you should believe this answer much more).
'controversy' becomes 'row' (both can mean a dispute).
'over' says the letters should be written in reverse.
'democrat' becomes 'd'.
'row' written backwards gives 'wor'.
'watch'+'wor'+'d'='WATCHWORD'

Can you help me to learn more?

(Other definitions for watchword that I've seen before include "Slogan" , "rallying-cry" .)
