Reason I say it’s fishy is because CNN is the only poll to find Obama leading among independents.

(CNN) – With a week and a half to go until Election Day, a new poll indicates the race for arguably the most important battleground state remains very close.

According to a CNN/ORC International survey released Friday, President Barack Obama holds a four point advantage over Republican nominee Mitt Romney in the contest for Ohio’s much fought over 18 electoral votes.

Fifty-percent of likely voters questioned in the poll say they are backing the president, with 46% supporting the former Massachusetts governor. Obama’s four point advantage is within the survey’s sampling error. The survey was conducted Tuesday through Thursday, entirely after Monday’s final presidential debate.
