Is Obamacare really that unpopular?

The GOP has long been claiming that Obamacare should be defunded/rescinded because it's unpopular, and the polls seem to back them up. Real Clear Politics shows that the polls are running on average about 50% opposed, 40% in favor, and 10% undecided. The Kaiser Family Foundation polls show a slimmer majority in opposition, but still a majority.

But the Kaiser Family Foundation recently posted something else that shows that many Americans don't know what's actually in Obamacare, but when they find out they tend to broadly support it.

Here are some things in the Affordable Care Act that Americans support:

• Allowing young Americans to stay on their parents' coverage. Since this was implemented, the percentage of uninsured young people (ages 19-25) fell from 48% in 2010 to 21% in 2012. 76% of Americans support this, including 69% of Republicans.
• Tax credits to small businesses to buy insurance. According to an article in Forbes, many small businesses are already eligible for tax credits of up to 35 percent. After January 1, 2014, the credit increases to 50%. 88% of Americans support this, including 83% of Republicans.
• Close Medicare “doughnut hole”. 81% of Americans support this, including 74% of Republicans.
• Health insurance exchanges. 80% of Americans support this, including 72% of Republicans.
• Subsidy assistance to individuals. 76% of Americans support this, including 61% of Republicans.
• Medicaid expansion. 71% of Americans support this.
• Guaranteed issue (no pre-existing conditions). 66% of Americans support this, including 56% of Republicans.
• Medical loss ratio. 65% of Americans support this, including 62% of Republicans.

The GOP knows (and Republican Senate Minority leader Mitch McConnell has said) that it's easier to prevent something from happening than it is to undo it later. It appears to me that Obamacare is likely to be pretty popular once the word gets out, and my in fact eventually be thought of as being virtually untouchable, like Social Security and Medicare.
