The choice of these nominees may result in two significant shifts. One is a recoloring of the familiar political map. When Trump was running close to even, he was threatening to win previously safe Democratic states. Clinton is now threatening to win previously safe Republican states. The static polarized partisan lines may be shifting.
The other is the opening of new fissures in both parties. Trump enthusiasts and Never Trump critics are already embarked on a civil war. Bernie Sanders enthusiasts are understandably furious about what WikiLeaks has revealed that Clinton and top aides have said in e-mails and speeches.
A Bloomberg poll asked Republicans and Democrats which of several figures should be the face of their party nationally if their nominee loses. A plurality of Democrats, 32 percent, said Hillary Clinton, and 6 percent said Tim Kaine. But 31 percent said Bernie Sanders, and 23 percent said Elizabeth Warren.
Among Republicans, 24 percent said Donald Trump, far below the percentage supporting him against Clinton. But a total of 71 percent picked the more conventional conservative alternatives Mike Pence, Ted Cruz, Paul Ryan, and John Kasich.
