Republicans oppose the Affordable Care Act, also known as Obamacare, for several reasons, citing higher taxes and an increased role of federal government as primary reasons for disliking the national health care policy. Republicans raise concerns that Obamacare reduces the economic output and efficiency of the United States by driving up taxes and putting the financial and regulatory burden of compliance on companies, forcing them to spend more money and time dealing with the costs and recordkeeping of employees' health care. They argue Obamacare forces companies to hire more part-time workers rather than full-time workers, and reduces the quantity of health care benefits for employees.
In addition to increasing taxes and expenses for companies, some Republicans express concern that Obamacare violates the Constitution of the United States. However, the Constitution gives state and federal governments the responsibility of protecting the health, safety and welfare of all citizens, making that claim void. The Republican Party prefers a minimalist role of the federal government in their personal lives and business affairs. They criticize Obamacare for increasing the presence of the federal government in citizens' lives by requiring health care coverage for all citizens, and playing an active role in monitoring and enforcing the provisions of Obamacare. Despite arguing against Obamacare in whole, many Republicans support individual provisions of Obamacare, such as extending coverage to children up to age 26 and eliminating health care exclusions for people with pre-existing conditions.
