In caucus, leads Reilly almost 2-1. In his first test as a candidate for governor, political newcomer Deval Patrick scored a sweeping victory at Democratic caucuses yesterday, trouncing Attorney General Thomas F. Reilly, a two-term statewide office holder. Delegate slates pledged to Patrick, the former top federal civil rights prosecutor and business executive, rolled up margins at local party meetings that will give him close to a 2-to-1 advantage over Reilly in the count of committed delegates, according to several Democratic Party strategists around the state.
