Washington (CNN) — Thursday’s landmark Supreme Court decision upholding the country’s health care law appears to have had exactly zero impact on the presidential election so far, and has produced virtually no change in opinions on President Barack Obama or Republican challenger Mitt Romney, according to a new national poll.

And while the CNN/ORC International survey released Monday indicates the president with a very slight three point edge over Romney among registered voters nationwide, the presumptive GOP nominee appears to hold an eight point advantage among voters who live in the 15 states considered in play in the race for the White House. […]

About a third of all Americans live in states that are not considered safe Republican or safe Democratic strongholds, including toss-ups states (like Florida and Ohio) as well as states that lean toward one presidential candidate but could ultimately wind up voting for his rival. In those 15 “battleground states,” the poll indicates that Romney currently has a 51%-43% advantage over the president among registered voters, if the election were held today.
