<p>BATON ROUGE - Democrats complained Thursday that Republicans were attempting to suppress black voter turnout in Saturday's election through a radio ad that purported to be from a group of District of Columbia school parents.</p>
<p>The ad, featuring a black woman, asks Louisiana voters "to say no to the Democrats," specifically saying U. S. Sen. Mary Landrieu, D-New Orleans, is opposed to vouchers to allow D.C. parents to use public funds to send their children to private schools.</p>
