McLean resident Terry McAuliffe, the former chair of the Democratic National Committee and of the Hilary Clinton for President campaign, will be the keynote speaker at the April 3 Falls Church Democratic Committee’s annual Jefferson-Jackson Dinner, committee spokesmen indicated this week. McAuliffe is expected to run for governor of Virginia in 2013, and will enter the fray as the front-running Democrat after he failed to win the Democratic nomination for the governor’s race in 2009, losing to State Sen. Creigh Deeds.
