How did the "rule of reason," supported by William Howard Taft, differ from Theodore Roosevelt's New Nationalism? The New Nationalism would seek government control over telephone and telegraph rates while the "rule of reason" would not.
The New Nationalism would back stronger government power to bust trusts while the "rule of reason" would weaken that power.
The New Nationalism would weaken the hard line set by the Sherman Antitrust Act while the "rule of reason" would strengthen it.
The New Nationalism would allow trusts to squeeze out smaller businesses while the "rule of thumb" would not.
