Answer:
The advantage was that the political ideologies were defended.
Step-by-step explanation:
A splinter party was made up of politicians who did not have their convictions and political ideologies defended by either of the two existing parties. Thus, the advantage of joining a splinter party was to have your political ideas defended and supported, without being forced to submit to Democratic or Republican ideologies. Thus, there was more political freedom in relation to the positioning of guidelines.
