Preferred Prime Minister

Note: Polls phrase this question as "Who should be leader of the LDP for the next term?" or "Who should be Prime Minister for the next term?", including Opposition Leader Yukio Edano only in the latter case. Because of this, some polls excluded Shinzō Abe (even while he was the incumbent), as he had already been elected as LDP leader three times, the maximum presently allowed under party rules.
