Following Donald Trump's win in the presidential election, Republicans have solidified control over both the House and Senate. This unified governance enables Trump to pursue major policies, including tax reform and immigration adjustments, while facing internal divisions and a slim majority. Key congressional races in traditionally blue districts contributed to this GOP success. However, challenges remain, including ongoing investigations involving prominent party members and debates over U.S. foreign policy commitments. The Republican Party's direction will be shaped by managing these dynamics as they prepare for a potentially turbulent legislative landscape.
