The minutiae of the proposals will also need reconciliation. The House, for example, added $173 million to its original $3.65 billion, the bulk of which — $154 million — was intended to backstop hundreds of proposed earmarks. The largest, according to an analysis done by the business-backed Massachusetts Taxpayers Foundation, would put $50 million toward what the bill calls “economic development improvements to transit stations in Norfolk County,” without specifying what the projects may be.
