I did a quick piece analyzing the polling averages (both a simple average, and a time-weighted average giving more recent polls higher weighting) and it confirms John Connolly as the clear leader with 15.0%, Marty Walsh in second with 11.6%, and Charlotte Golar Richie and Dan Conley virtually tied with 9.7% and 9.6%, respectively.
