Gov. Dannel P. Malloy could hardly be less popular if he tried. And he often seems to be trying. The last time Quinnipiac University took the public’s temperature, his approval rating was below 25 percent. Republicans chortle that he’s the least popular Democratic governor in the country. That hasn’t stopped him from trying to serve broccoli to people who want M&M’s. When we sat down for an editorial board about the will-not-resuscitate state budget Thursday, I recalled similar sessions over the past two decades, many while he was mayor of Stamford.
