Mark Halperin, this morning, via Politico: “Mark Halperin e-mails elaboration on a “Morning Joe” prediction: “Based on the current national environment, the enthusiasm gap, the state of the economy, the failure to materialize of a lot of what Democrats were counting on (health care law getting more popular, and ‘recovery summer’ taking hold), and polling in individual races, on the current trajectory, with no unexpected intervening events, Republicans are in a position to pick up as many as 60 seats.” Swing needed for control: 39 seats. GOP netted 54 seats in ‘94.”
