Most Americans think Obamacare is unconstitutional, and this feeling appears to be about principle -- a plurality say the law has had no effect on their lives. But even if they don't like President Obama's most famous legislation, they like him more than Mitt Romney (by 10 points!). And a huge majority wants to see an arrest in the Trayvon Martin case. Here's our guide to today's polls and why they matter.
Findings: A large number of Americans oppose Obamacare, but it's not clear how many. One poll finds the number to be 47 percent; another says 62 percent of Americans think it's unconstitutional for the federal government to make you buy health insurance.
Pollster: New York Times/ CBS News; Reason/ Rupe
Methodology: Survey of 986 adults from March 21 to March 25; survey of 1,200 adults from March 10 to March 20.
Why it matters: The Supreme Court is hearing epic arguments over the constitutionality of Obamacare this week. It's the president's signature domestic accomplishment, and there is near universal agreement that however the court decides the case, it will have a big impact on the election. The Reason poll also shows how you frame the question matters -- the poll finds 87 percent of Americans say the government does not have the authority to make them buy broccoli. It finds a majority of Americans support the part of Obamacare that prevents insurance companies from denying coverage to people with preexisting conditions -- a requirement the White House says can't survive without the individual mandate, because people would just wait till they're sick to buy insurance.
Caveat: The court can reflect public opinion, but it can also shape it. Also, a Suffolk poll shows a plurality, 40 percent, say Obamacare has made no difference in their lives.
