Conservatives may try to get Trump out of office in order to get Pence before the shit hits the fan.

"What would it take for Republican support for Trump in Congress to crumble as Nixon's did in August 1974, forcing his premature departure from office? Republican politicians would not turn against Trump en masse without the support of a significant share of Republican voters, and Republican voters would only do so if persuaded by key members of the conservative media. This is not a wholly unthinkable scenario; conservative media figures have ultimately soured on every major national Republican politician in the post-Reagan era, and their enthusiasm for Trump will at least diminish substantially over his tenure in office if the mistakes and failures continue to pile up. But it's hard to imagine influential conservatives abandoning Trump for Pence unless the Republican legislative agenda runs completely aground and Trump proves fatal to the Republican Party's electoral standing in 2018. Even then, Republicans may well still resist actually joining together with Democratic opponents to support Trump's impeachment or removal from office."
