Congressional Democrats voted for the over 1000 pages Affordable Care Act (ACA and also called Obamacare) after only having it in their possession for no more than 2 days. Do you really think they had the time to read all those pages? No Republican in the House or Senate voted for it. Well, the ACA’s individual mandate negatively affected enough people by making them lose their private health care insurance. Now through the ACA they must take new plans with higher premiums and deductibles.
The individual mandate caused a huge negative impact to the point that the affected voters just might choose not to re-elect the Democrats who voted the ACA into law. What happens when the employer mandate drops next year right around election time? See the cuts to work hours and jobs so far here.
