An analysis of voting records of US Senators shows that moderate Republican Senators Collins and Murkowski voted more similarly to Democrats than to Republicans.

This continues the analysis of Congressional voting records begun in Visualized grouping of US Congress members by similarities in their voting record.  The data is based on voting records collected at https://www.govtrack.us/.  The analysis and images are by me.

Here’s the image for Senator Collins (R-ME). Notice how the circle of blue Democrats is inside the circle of red Republicons, except for Senator Murkowski.
