Sci-fi author David Brin suggests that both U.S. political parties seize the general opportunity of the moment to institute more checks and balances on the president. Why use up political capital merely exchanging the 45th president for his vice president, Mike Pence?
Specifically, in his Facebook post, Brin proposes enabling a way to delay military orders and send them for congressional committee review; allowing for “the other party” to make the president's appointments for one afternoon a week; and creating a bipartisan "Fact Checking Institute."
During his campaign for office, the 45th president selected Mike Pence to be his vice president "as impeachment insurance," in Brin's analysis. In other words, Brin believes that Pence will also pose significant troubles for Democrats and their agenda, and that Trump "knew what he was doing" in picking Pence to discourage opponents from bringing down Trump.
