For a while, it seemed like you couldn’t find good Republican candidates for House races in Massachusetts. Now with Scott Brown’s win, they’re piling up, but unfortunately they’re clumping together: “South Shore Republicans have painted a bull’s-eye on U.S. Rep. William Delahunt. At least five people are considering a run for the 10th Congressional District seat he has held since 1997. The growing field includes three former and current state office holders – former State Treasurer Joe Malone of Scituate; state Sen. Robert Hedlund, R-Weymouth; and state Rep. Jeff Perry, R-Sandwich – as well as two political newcomers, Don Hussey of Hingham and Ray Kasperowicz of Cohasset.”
