The Obama administration's proposed power plant rule could benefit Democrats in key swing states, a poll released today shows. Residents of Pennsylvania and Virginia overwhelmingly support U.S. EPA's plan announced earlier this week to curb carbon emissions from existing power plants, according to survey results by the League of Conservation Voters. In Virginia, 61 percent of those asked said they approve of the rule, which would slash greenhouse gas emissions by 30 percent from 2005 levels by 2030. Pennsylvania respondents backed the plan by a similar 61-27 percent margin.
