Real Clear Politics has put Ohio in the "leans Obama" column, here, which puts Obama 5 Electoral College votes away from clinching victory, according to the polling and math as presented.
Recent discussion of polling has included charges that polling is oversampling Democrats, that polling amounts to "in-kind contributions" to Democrat campaigns by news organizations biased toward liberalism, that polling is campaigning in another form, that polling is disinformation designed to suppress the turnout of the Republican opposition, etc.
So remember this map after the election is over, the only poll that counts.
