I'm more concerned about what this says in terms of his confidence for Democrats to hold the House. He's the Chairman of the Budget Committee.
It can’t mathematically be done.
I mean, this is just blatantly inaccurate, especially if Democrats draw the lines far more aggressively than Republicans (especially in CA, IL, NY, MI, PA).
It’s not likely that Democrats hold the House but it’s certainly not 'mathematically impossible' and arguably not even considerably less likely than Democrats holding the Senate.
Based on what our redistricting commission has been churning out recently, Democrats would be pretty lucky to have a 7D-6R majority in a neutral midterm, let alone in a midterm that will presumably be favorable for the GOP.
