Rob McCord, a Montgomery County venture capitalist, easily defeated three opponents yesterday to become the Democratic nominee for state treasurer.

Thanks to name recognition built up through a massive TV ad campaign, McCord held off his closest rival, John Cordisco, the Bucks County Democratic Party chairman.

State Rep. Jennifer Mann of Allentown finished third, while Dennis Morrison-Wesley of Harrisburg, a former investment salesman, trailed the field, according to unofficial statewide results.
