Super PACs are increasing advertising spending in the closing stretch of Massachusetts’ governor’s race, with groups backing Republican Mike Minogue shifting their attention toward independent Andrea James, according to WBUR.

Meanwhile, political action committees supporting Gov. Maura Healey are spending on messages linking Minogue to President Trump, WBUR reported. The competing approaches put different candidates at the center of the outside groups’ advertising efforts as the race nears its conclusion.

The change in strategy among Minogue’s supporters brings James into the focus of their attacks. WBUR described the move as a shift in tactics by the financial forces backing the Republican candidate.

For the groups supporting Healey, the emphasis is instead on Minogue and Trump. Their advertising spending is aimed at associating the Republican gubernatorial contender with the president, rather than following the Minogue-aligned groups’ turn toward James.

The supplied WBUR summary does not specify spending totals, identify the individual committees or describe the advertisements in detail. It also provides no polling information or evidence of how voters have responded, leaving the effect of the competing advertising strategies unclear.
