Some of the delegates at the constitutional convention sought ways of shielding elected officials from the democratic pressures of the "mob." the selection process of which officials separated them from the demands of the people?

 the officials were presidents,senators and supreme court justices.
The president would be elected by an electoral college, while the senators would be elected by state legislatures. the supreme court justices would be appointed for life by the president with the approval of senate. The senators would be committed to public good because they served a bigger term than the state legislatures that elected them. The life tenure of the s,justices, protected them from the mob pressures.

Political forces often influence public opinion.
