A new poll on the Massachusetts special election for U.S. Senate shows Democrat Ed Markey with a 12-point lead over Republican Gabriel Gomez, with 49 percent supporting Markey and 37 percent supporting Gomez.

The poll, conducted by Harper Polling, a Republican-affiliated firm, on behalf of Conservative Intelligence Briefing, surveyed 498 registered voters in Massachusetts and found that while an overwhelming number of Democrats and Republicans support their party’s candidate, independent voters are split at 41 percent on Markey and Gomez.
