Lakian told his supporters gathered at the Computer Museum in Boston to support Romney and implored his well-wishers to keep the flat-tax proposal alive.
"The tax issue is not going to go away. It's idea whose time has come," Lakian said.
Romney campaign workers said they will enjoy winning yesterday's primary, but they realize that a much tougher race looms ahead beginning today.
"It will be a true horse race and most of the polls show as dead even," said Christopher R. DeVany, Romney's mid-state co-coordinator.
"But we're also aware of the political reality that Democrats outnumber Republicans three to one [in Massachusetts]," DeVany added.
Romney has both the funds and organization to challenge Kennedy in a race which promises to be both highly publicized and costly, DeVany said.
In the seven weeks leading up to election day, Romney plans to raise an additional $4 million to more than double his campaign funds. And the Republican nominee expects prominent members of his party to campaign for him in the Bay State, DeVany added.
State treasurer Joseph D. Malone '78 introduced Romney last night and the GOP nominee was joined on stage by his parents, and his five sons and one daughter in Law.
Romney comes from a distinguished political family in his native Michigan. His father, George, was governor of the state from 1962-68 and his mother, Lenore, ran unsuccessfully for a U.S. Senate seat in Michigan in 1970.
