Despite Lukewarm Support from Some National Republican Figures When Donald

Despite lukewarm support from some national Republican figures when Donald Trump was running for president, a Republican-controlled Congress still managed to pass a major tax reform package in late 2017, one that reduced taxes for businesses and wealthy individuals.What did this suggest about how unified or one-party government, as opposed to divided government, works at the federal level?

A) One-party government results in more effective use of the Constitution's checks and balance system, and thus better policies.
B) It suggests that the overwhelming influence that corporate and affluent interests have over American elected officials supercedes party differences.
C) It suggests that major pieces of legislation are more likely-although still not guaranteed-to pass when one party controls the White House and Congress, as contrasted with greater likelihood of gridlock in divided government eras.
D) Tax cuts are popular and thus easier to pass, no matter what party is in charge of either the White House or Congress.
