(TOKYO) — Japanese Prime Minister Shinzo Abe was re-elected as head of his ruling Liberal Democratic Party in a landslide Thursday, paving the way for up to three more years as the nation’s leader. Abe handily defeated his sole challenger, Shigeru Ishiba, a former defense minister. Abe won 553, or about 70%, of 807 votes. The decisive victory may embolden Abe to pursue his long-sought revision to Japan’s U.S.-drafted pacifist constitution, although the hurdles remain high and doing so would carry political risks. “It’s time to tackle a constitutional revision,” Abe said in a victory speech.
