A potential "blue wave" of Democratic success in Massachusetts could bury the opposition party even further, as Republicans currently hold about 15 percent of seats in the House and Senate. This represents a significant decrease in their power as a small but not inconsequential presence that ensures open debate and public votes. The 2006 anti-Bush midterms saw the House GOP drop from 21 seats to 19 seats, the 2008 Obama wave saw them lose another three seats, and the 2018 anti-Trump surge saw the loss of another GOP Senate seat and two more in House. If voters return Gov. Maura Healey to the office as expected, the GOP will have very little influence over Massachusetts policy.
