Yes the the Articles of Confederation did not fully reflect the principle of "republicanism" because of the following underlisted points:
a- it stated one political party should maintain most of the power
b- voters had no say in who represented them in federal government
c- state governments were inferior to the national government
d- representatives from each state government were elected by the people
Explanation:
a. It stated one political party should maintain most of the power - Articles of Confederation, first U.S. constitution (1781–89), which served as a bridge between the initial government by the Continental Congress of the Revolutionary period and the federal government provided under the U.S. Constitution of 1787. Because the experience of overbearing British central authority was vivid in colonial minds, the drafters of the Articles deliberately established a confederation of sovereign states. The Articles were written in 1776–77 and adopted by the Congress on November 15, 1777. However, the document was not fully ratified by the states until March 1, 1781. It was the article that called the representatives of the thirteen states to agree to create a confederacy called the United States of America under one party system.
b. Voters had no say in who represented them in federal government because the states merely have the right to select and send two to seven delegates to Congress each year. since they are selected not voted, the voters have no right of electing their representatives in the confederation.
c- state governments were inferior to the national government - Yes the  state governments were inferior to the National government in the sense that  States are not allowed to conduct relationships with foreign nations without the permission of congress. They cannot wage war, negotiate peace, raise an army or navy, conduct diplomacy, or make an alliance with another state. However, they can make imposts on goods, as long as they do not interfere with foreign treaties. States must keep a local militia, and they may wage war if they need to quickly defend themselves.
During war, states have the right to appoint officers of colonel rank and below. Congress pays for war from a treasury that states contribute to relative to the value of land in their state.
Congress has the sole power to deal with foreign nations, including making war and peace, and to deal with Indian (Native American) affairs. Congress must maintain uniform standards of coins and measures, make the rules for the army and navy, and run the post office. Congress will help resolve interstate disputes only as a last resort, and has the sole right to hold trials for crimes committed at sea.
d. Representatives from each state government were elected by the people - No the representatives from each state are selected not elected. The provision states thus: States have the right to select and send two to seven delegates to Congress each year. Each state has one vote in congress, and delegates can only serve for a period of three years in any interval of six years. Delegates have certain privileges while serving in Congress. They are guaranteed the right to freedom of speech and are immune from arrest for most petty crimes.
