The idea that an individual has a tendency to support the beliefs and practices of his own political party rather than those of the other party is called a multi party system. linkage. interest group. partisanship

I believe the correct answer is partisanship.
Partisanship refers to bias, to people who are partial to their own party, believe in it, fight for it, and don't support anything else other than that particular party. 
A multiparty system just means there is more than one party involved; linkage refers to connections between parties; interest group is a group trying to persuade others to believe its cause.
