RICHMOND, Va. (AP) _ Virginia apparently will not be backing a convention of states to amend the U.S. Constitution this year. Del. Scott Lingamfelter withdrew his resolution urging Congress to call a constitutional convention Thursday. He said the measure did not have enough support in the House or the Senate to pass. A similar proposal is pending in the Senate, but Lingamfelter’s move means that measure is likely doomed as well. The Prince William County Republican said he will try again next year. Lingamfelter said the Constitution needs to be amended to rein in a federal government that has become too powerful. Opponents fear that a constitutional convention would do more harm than good. Only three states have petitioned Congress for a constitutional convention. It takes 34.
