Perhaps you should try some spelling variations:
"independent politician" » "independent politicas", "independent political", "independe politician", "independing politician"
"independing politician" » "independing politicas", "independing political", "depending politician"
"dependent politician" » "dependent politicas", "dependent political", "depende politician", "depending politician"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"independent politician\") OR (\"independing politician\"))) OR (\"dependent politician\"))~".
• Removing quotes may allow a broader search: (((( independent politician ) OR ( independing politician ))) OR ( dependent politician ))~.
• Adding a wildcard symbol may retrieve word variants: (((("independent politician") OR ("independing politician"))) OR ("dependent politician"))*.
