At the rate this is going, Republicans could soon start passing Constitutional amendments along party lines.
Not yet as they dont have close to 290 seats in the House , and they likely wont get it .
Honestly, in a scenario where the GOP is winning Senate races in California and New Mexico, I'd expect them to hit 290 in the House. And while there's no indication here about state legislatures, if the governorships are any indication, the GOP could be on their way to controlling 3/4 of states by 2020.
