By the end of today, Boston will have its first new mayor in 20 years, and according to the latest polls, the favorite to succeed Democrat Thomas Menino is anyone's guess. The most recent numbers from Suffolk University and the Boston Herald put state Rep. Marty Welsh ahead by three points, while a recent poll from Boston's WBUR radio station gave City Councilor John Connolly a two-point lead. Either way, it's quite the comeback for Walsh, who was down by seven points at the beginning of October. It's possible the turnaround is thanks to outside money that has given Walsh's campaign a boost in recent weeks.
