In 2006, the Greenwich millionaire had an issue that energized the Democratic base against US Sen. Joe Lieberman. Lamont won the primary, disappeared on a vacation to Vermont when he was hot, then was defeated by Lieberman running as an independent. Lieberman’s appearances in the state have been few and far between since then, which some would say is a good thing. But what’s Lamont have to offer this time, besides threatening to ignore the state’s campaign-finance program because it might not give him enough cash to campaign against GOP rainmaker/corporate takeover king Tom Foley, another Greenwich millionaire? It’s up to him to offer something solid besides a willingness to shower money on Connecticut TV stations. We’ll see what it looks like at 11 this morning in the scenic Old State House.
