Here’s an excellent analysis from Da Tech Guy.

Excerpt:

For the last two weeks we have been treated to the narrative that Barack Obama is surging at the polls, Mitt Romney is in trouble and unless there is a massive change in direction it is all over.

Simply put this is a lie.

Of all the polls you have seen, there is one poll that has gotten no attention, it is a poll that has been taken monthly, it is a poll that Doug Ross spotted and promoted on his site. It is the Rasmussen Poll of party identification.

They have party identification results online dating back to 2004.

Here are the recent numbers:

It’s a 3-4 point advantage for Republicans.

Da Tech Guy continues:

At no time during the year do the Democrats have a registration advantage vs republicans, the gap closes in July & re-separates in August. The low point for the GOP was July for 34.9 and the high August at 37.6 For democrats the high was 34.0 in June & July the low was 32.4 in Feb

What does this mean for November? It means a lot.

The Democrats won 2 election in this period 2006 & 2008 with a 6.9 advantage in 2006 & a 7.6 advantage in 2008.

There is no example of the Democrats winning since 2004 with an advantage less that 6.9.

The GOP won two elections in this period 2004 with a -1.6 disadvantage & 2010 with a 1.3 advantage. This means the GOP has proven it can win with not only a small lead but with an actual disadvantage. Additionally with an advantage of only 1.3 they pulled off the biggest house swing in my lifetime.

Can these number change? Well the biggest 1 month swing I’ve seen is 4.2 Oct-Nov in 2010 the biggest 3 month swing was Dec 2007-Feb 2008 6.9 in favor of Democrats at the rise of Obama.

Tell me with the economy in the tank, and the new trouble in the Middle East, what is the prospect of a swing of that size to the Democrats happening again right now? Moreover even if that record registration swing repeated itself right now this would give democrats an advantage of only 2.6 points.

I’ve covered a lot of national polls on this site over the last year and all those polls ABC, CBS, NBC, FOX have one thing in common.

Not a single one of those polls had a sample with a GOP advantage.

And here’s what the mainstream media have been doing with their polls:

Only the Rasmussen Reports poll is accurately sampling voters based on party identification.

That’s why Obama looks like he’s winning. He’s not.
