Gov. Ned Lamont has said he doesn’t support a push by Senate President Pro Tem Martin Looney to raise taxes on high-end homes. Looney has proposed what he’s calling a mansion tax to increase property tax on homes worth over $430,000; the money could go to supporting struggling cities. But Lamont told the º£½Ç»»ÆÞ Business and Industry Association Tuesday that he won’t back new taxes and he doesn’t think the bill is going anywhere.
