Over at MassPoliticsProfs, Peter Ubertaccio reflects on the re-emergence of former Gov. Bill Weld as a booster for gubernatorial candidate Charlie Baker, and says Weld has never toed the party line.

This isn't the first time that Weld has run afoul of the puritans of his party.

In 1992, he tried to move the national party away from its ardent pro life platform. He was booed at the Houston Convention.

In 1994, on his way toward a historical reelection win, the Governor was accused of doing very little to assist Republicans down ballot.

He also famously joined a group of Republicans—from former Reagan Solicitor General Charles Fried to former Secretary of State Colin Powell and former spokesperson for George W. Bush Scott McClellan—who endorsed Barack Obama over the McCain-Palin ticket in 2008.
