It’s refreshing to see Bob Casey taking a principled stand against the Obama administration’s onerous new emissions rules. Even though Pennsylvania’s senior U.S. senator supports many measures to combat “climate change” — with which, of course, we would disagree — he’s astute enough to know that what the president proposes would not only harm the Keystone State economy but scotch waste-coal power generation that will do more harm to the environment than good. … The Internal Revenue Service is at it again. Actually, it appears to never have stopped its Orwellian Big Brother ways. Thomas Lifson at the American Thinker reports that the IRS has been monitoring conservative blogs as fodder to fight back against being forced to reveal the identities of IRS employees involved in targeting conservative organizations for special scrutiny. Naming names supposedly would be a threat to those employees, the IRS contends. As Mr. Lifson reminds, this is the same IRS that claims it’s so understaffed that it can’t collect unpaid taxes or search for Lois Lerner’s infamously missing emails. … The New York Times’ Nate Cohn concludes that voter ID laws haven’t been swinging elections and that opponents have vastly overstated the “voter suppression” that these laws supposedly cause. Sayeth Mr. Cohn, “The impact of voter ID laws is basically indiscernible in the results.” Which confirms what we’ve long said about “progressives” — they’re all cluck.
