Fact check: Who was last republican senator from Massachusetts

1. Summary of the results

Based on the analyses provided, Scott Brown was the last Republican senator from Massachusetts. Multiple sources confirm that Brown served as a Republican U.S. Senator from Massachusetts from 2010 to 2013 ^{[1] [2]}. His tenure ended when he lost his re-election bid to Elizabeth Warren in 2012 ^[3].

The sources consistently identify Brown as a former Republican Massachusetts senator who later moved to New Hampshire to pursue political opportunities there ^{[4] [2] [3] [5]}. This makes him the most recent Republican to represent Massachusetts in the U.S. Senate.

2. Missing context/alternative viewpoints

The original question lacks important historical context about Massachusetts' political landscape. The sources reveal that Massachusetts currently has 4 Republicans and 36 Democrats in its state senate ^[6], highlighting the state's strong Democratic lean at the state level as well.

Additional missing context includes:

• Scott Brown's political trajectory after Massachusetts - he relocated to New Hampshire and ran for Senate there multiple times ^{[2] [3] [5]}
• The duration of Republican absence - it has been over a decade since Massachusetts had Republican representation in the U.S. Senate
• The broader historical pattern - Massachusetts has been predominantly Democratic in federal representation for an extended period

3. Potential misinformation/bias in the original statement

The original question itself contains no apparent misinformation or bias - it is a straightforward factual inquiry about political representation. However, the question could be interpreted in two ways: referring to either U.S. Senate representation or state senate representation. The analyses focus primarily on U.S. Senate representation ^{[1] [4] [2] [3] [5]}, while only one source addresses state-level representation ^[6]. This ambiguity could lead to confusion, though the context strongly suggests the question refers to federal representation given the historical significance of Scott Brown's tenure.
