Could be this one. Especially if we see both parties fracture (which is quite likely)
The Republicans are more likely to fracture this time. Demographics might hurt the Republicans this time because the youngest voters associate the Republican Party with heavy personal debt (due to high-cost college loans) and low pay for those with little education (and often for those with much education). People in hock up to their eyeballs for the means of sustenance tend to be very far to the Left on economics. The Millennial Generation has little cause to support Republicans who offer more of the same.
