A critical dynamic faces Senate President Donald Williams and Speaker of the House James Amann during this legislative session. They are Democrats with a duty to set up their party’s gubernatorial nominee to win against Gov. M. Jodi Rell, whether it is John DeStefano or Dannel Malloy. But they also need Rell’s signature on their bills, not to mention her assent to their budget and bonding requests. So with the governor maintaining sky-high approval ratings, the temptation exists for Democratic leaders to leverage Rell’s need to stay on the right side of popular issues in an election year. They could cut favorable deals on legislation, and essentially hang Malloy and DeStefano out to dry.
