August 29, 2008 McCain to Reveal His Vice Presidential Pick Friday -------------------------------------------------- http://enews.voanews.com/t?ctl=1DEF1B8:A6F02AD83191E16040ACB001464A169E98CBE7246176B735& Top choices are believed to be Minnesota Governor Tim Pawlenty and former Massachusetts Governor Mitt Romney John Mc Cain and his wife Cindy wave as they board the Straight Talk Air campaign charter airplane, 28 Aug 2008Republican presidential candidate John Mc Cain will celebrate his 72nd birthday Friday by introducing his vice presidential running mate at a rally in Dayton, Ohio. Mc Cain's campaign announced Thursday the Arizona senator had made his choice, but would not reveal who the person is. Mc Cain himself ignored reporters' questions when he and wife, Cindy, arrived at a Phoenix, Arizona airport to fly to Dayton. Speculation has grown that Mc Cain will either choose Minnesota Governor Tim Pawlenty or former Massachusetts Governor Mitt Romney, who waged a bitter fight against Mc Cain for the Republican nomination. Pawlenty canceled a number of media appearances Thursday in Denver, Colorado, where Democratic rival Barack Obama accepted his party's presidential nomination. But it was unclear if there was any connection to the vice presidential pick. Senator Joe Lieberman Another possible choice, Senator Joe Lieberman of Connecticut, is drawing considerable fire from hardline conservatives over his support for abortion rights. Lieberman was Democrat Al Gore's vice-presidential running mate in 2000. He has since become an independent due to his strong support for the U.S.-led war in Iraq. Former Pennsylvania Governor Tom Ridge and U.S. Senator Kay Bailey Hutchison are also thought to be under consideration. Mc Cain aired a television advertisement Thursday congratulating Obama on a "job well done" for his historic nomination. But in a separate statement, Mc Cain's campaign Thursday mocked the classic Greek-style columns on the stage for Obama's speech. The veteran Arizona lawmaker will formally accept the Republican presidential nomination at the party's national convention in Minneapolis-St. Paul, Minnesota.
