Like petulant children, Congressional Republicans shut down the government because they don't like Obamacare. More to the point, they don't like Obama. Obamacare is primarily a Republican program, modeled after the Massachusetts program signed into law by Mitt Romney. It provides health insurance to all through private insurance companies. When bringing the ACA into law, Obama compromised wholeheartedly with Republicans; he even abandoned the key element, a single-payer public option. The Republicans who want to destroy Obamacare by shutting down our Federal government are saying "Obama needs to compromise." Our democracy can not yield to terrorists within the halls of Congress who want to destroy our system of government.
If Republicans wanted to fix Obamacare, they could pass a specific bill to fix it. They tried 42 times to kill Obamacare and failed. Now they are attacking our governmental budget and national economy. It's treason.
