Go in with Jims sort of patriotism (8)
I believe the answer is:
jingoism
'patriotism' is the definition.
(jingoism is a kind of patriotism)
'go in with jims sort' is the wordplay.
'with' means one lot of letters go next to another.
'sort' is an anagram indicator.
'go'+'in'='goin'
'goin' put after 'jims' is 'jimsgoin'.
'jimsgoin' is an anagram of 'JINGOISM'.
'of' is the link.
(Other definitions for jingoism that I've seen before include "Extreme patriotic activity" , "Unthinking patriotism" , "showing a sort of prejudice" , "Extreme and vociferous patriotic attitudes" , "Aggressive patriotism of English sort" .)
