House Speaker Joe Aresimowicz, D-Berlin, said Tuesday he intends to call a vote next week on legislation making an initial commitment to implementing electronic highway tolls, despite Republican opposition that could brand Democrats as the party of tolls. Aresimowicz said he did not fear Republican campaign mailers accusing Democrats of opening Connecticut motorists to tolls on every major highway, saying the counter message would be to label Republicans as choosing higher commuter bus and train fares and a freeze on transportation repairs as preferable to tolls.
