DILMI Samah, METTAH Hayat2019-01-162019-01-162017-06an2017/026http://dspace.univ-msila.dz:8080//xmlui/handle/123456789/6997Abstract In its early days, the Republican Party favored a large government to end the institution of slavery and ensure a better life for all Americans without regard to race .Over time, however, the party’s policies changed and Republicans championed a small government. Additionally, the party witnessed the emergence of extreme groups such as the Radical Republicans who represented the far left wing and the Neoconservatives who embodied the far right wing. Donald Trump, the current president of the United States who belongs to the far right wing has been the appropriate example to depict the rise of the radical voice in the party. In the present study we try to answer questions as what were the main shifts in the Republican Party's principles ? and what were the reasons for the rise of the new radical Republican Trump ? . The ultimate aim of the study is to analyze the factors that paved the way for the emergence of some radical voices in the party, especially the factors that helped Trump’s rise and thus the far right wing. The analysis shows that Trump gave birth to many radical ideas and that the main reasons behind the success of Trump are the effectiveness of his message and common people’ hatred to American politicians.otherlarge government-analyzeThesis
