Earlier this afternoon Fox News posted their first likely voter poll of the campaign, which shows Mitt Romney leading Barack Obama 45%-44%.  Many of us were wondering how the polling would look once the pollsters switch to a likely voter screen – a model which is almost always more favorable to Republicans than a poll of registered voters.  This poll of 1,007 likely voters is a far cry from the last Fox News poll of 930 registered voters, which showed Obama with a 9 point lead.  Obviously, that poll was taken during the nadir of Romney’s campaign and before he got a boost from picking Paul Ryan as his running mate, but clearly the LV model makes a difference.  In this case, it gave Romney a 3-point bump (Obama is up 2 when including RVs).

The likely voter screen was comprised of 42% self-described Democrats 38% Republicans and 18% Independents.  Presumably, this does not reflect the actual affiliation of those surveyed because registered Independents comprise a greater share of the electorate than 18%.  I’m presuming that some of those tallied as Republicans or Democrats are registered Independents who lean decisively in one direction.

Almost every likely voter poll taken until now has shown Romney and Obama deadlocked, even while RV polls were showing Obama with a significant lead.  It will be interesting to see what happens when other RV pollsters switch over to an LV model.

Here are some of the key findings from the Fox News poll juxtaposed to some historical data.  It’s useful to become familiar with these data points as more LV polls begin to surface.
