Input: (CNN) If current opinion polls are to be believed, this Sunday voters in Japan will return Prime Minister Shinzo Abe to office with an increased majority, putting the 63-year-old conservative on track to become the longest-serving leader in the country's post-war history. An election victory would also provide Abe with what may be his best, and possibly last, chance to secure the majority needed to begin the process of revising Japan's pacifist constitution. Abe, a deeply divisive and unpopular figure within many parts of Japan, has so far struggled to engage voters beyond his core support. In the weeks preceding the election, approval ratings for Abe's Liberal Democrat Party (LDP) have stood at a mere 37%, a low bar even by Japanese standards, where enthusiasm for political parties remains apathetic at best.Voter turnout could drop below 50% for first time in postwar historyLack of credible opposition and voter apathy expected to result in Abe victory
