Some new source of revenue must be established now and the dollars set aside, especially in a state that already has dumped more than $30 billion in pension debt on future taxpayers. For Lamont, that new source of revenue is a network of tolls – albeit a much smaller one than he proposed in February. That “reality” is a Democratic majority in the House that proclaims it’s ready to adopt tolls now, and a Democrat-controlled Senate that might be able to pass tolls by the narrowest of margins — but doesn’t want to do so without Republican support. The GOP remains wary of any tolling network, even one much smaller than the system Lamont proposed in February . But Republican leaders also concede there’s appeal in the governor’s plan to leverage huge sums of federal money — cheaply — right now.
