(Boston)  The Massachusetts Senate has begun debating a bill to let the governor name an interim replacement for the late Sen. Edward Kennedy.

Republican lawmakers have twice delayed action on the measure. They opted not to block it for a third day.

If approved, the bill would require a final vote in both chambers Wednesday before heading to Gov. Deval (deh-VAHL’) Patrick. The House gave initial approval last week.

Patrick supports the measure and could name an appointment when he signs the bill.

The appointee would serve until voters pick a permanent replacement Jan. 19 special election.
