Two-thirds of Maryland voters favor doubling the $1-a-pack cigarette tax to expand health insurance coverage, according to anew state poll.

The poll is part of a renewed push by a coalition of groups called the Maryland Citizens? Health Initiative to raise tobacco taxes to both reduce smoking and cut the number of people without health insurance. The coalition, with AARP in the lead, is beginning a $100,000 statewide campaign of print and radio ads to drum up support for the plan.
