(CNN) -- Thursday's Supreme Court ruling upholding President Barack Obama's health care law has Americans divided, according to the first survey following the landmark decision.
Friday's poll from USA Today/Gallup showed 46% of Americans agree with the court's ruling, with 46% saying they disagree. Opinions were predictably split along party lines: 79% of self-identified Democrats agreed with the decision to uphold the president's law, while 83% of Republicans disagreed with the ruling.
Independents mirrored the poll's larger results - 45% agreed with the Supreme Court's decision, and 42% disagreed.
A CNN/ORC Poll taken at the end of May indicated 43% of Americans favored the Affordable Care Act, while 51% opposed the measure. Broken down, 13% said they opposed the law because it was not liberal enough, while 34% opposed it because it was too liberal.
On Thursday, the Supreme Court upheld Obamacare, saying the individual mandate, while not constitutional under the Commerce Clause of the constitution, was valid if viewed as a tax.
Following the decision, Mitt Romney, the presumptive GOP nominee, renewed his vow to eliminate the law if elected president, and House Republicans scheduled a vote to repeal the measure in July. That effort, which could pass the Republican-controlled House, isn't expected to get anywhere in the Democrat-controlled Senate.
The Gallup survey taken after the court's ruling showed 31% of Americans said they wanted the entire law repealed. Twenty-one percent advocated repealing parts of the law.
Another 25% said the government's role in health care should be expanded beyond the level stipulated in Affordable Care Act.
The Gallup poll was taken June 28 by telephone from 1,012 adults. The sampling error was plus or minus four percentage points.
