Gov. Ned Lamont and Democratic legislative leaders recently criticized the Senate GOP plan — which avoids tolls and drains 60% of the state budget reserves — for leaving Connecticut dangerously vulnerable. Democrats, meanwhile, have crafted a plan to pump $20 billion into transportation over the next decade — in part by tolling trucks, but not cars. But that plan also hinges on Connecticut’s economy remaining rosy until late 2024. But what they didn’t say last week was that to maximize their plan, there must be budget surpluses ranging between $321 million and $467 million every year from 2021 through 2024.
