NBC News: “Lt. Gov. John Fetterman holds the lead in a rare early poll of the Pennsylvania Democratic Senate primary, winning 40 percent of likely Democratic voters, with Rep. Conor Lamb, D-Pa. – who is weighing a bid but isn’t officially a candidate – in second place with 21 percent. The survey was conducted by Data For Progress, a progressive firm tapped by the Fetterman campaign, and first reported here by NBC News. It’s based on a weighted sample of 302 likely Democratic primary voters and has a margin of error of plus or minus 6 percentage points.”
