About 22 percent of Alabama's voters turned out to approve a constitutional amendment withdrawing $437 million from a state trust fund to help balance the state General Fund budget for the next three years. Unofficial returns compiled by The Associated Press show about 600,000 of Alabama's 2.67 million voters participated in Tuesday's special election, and they approved the constitutional amendment 65 percent to 35 percent. The turnout was in line with the 20 to 21 percent predicted by Alabama's chief election official, Secretary of State Beth Chapman. She said she's pleased that about one-fifth of Alabama voters participated, but she wishes the turnout had been higher. Copyright 2012 The Associated Press.
