Rather than using only Rasmussen, which has shown the worst numbers for Obama consistently throughout the year, I would challenge you to provide non-Rasmussen evidence that the non-Republican public is jumping ship on Obama. Indeed, nearly all of his drop in numbers has come from Republicans. I think there’s an important distinction which you do not draw between Congressional Democrats wavering and where public opinion is actually at on these issues. Despite the expected trepidations over individual controversial elements of the health care bill, like how to pay for it, the structure of the insurance exchange, a public option, among others, a strong majority still backs major structural reform – something Republicans are using bad faith arguments to block. Support for a public option remains untouched, lingering in the 2/3 range. I would encourage Republicans and their sympathizers to continue to falsely believe, well into the midterm elections, that skittish Democratic votes in the Senate are evidence that the underlying proposals are unpopular. Please run against change again. And it’s not smug to point out that historically low support for the GOP, unchanged throughout the year, combined with Democrats’ monopoly over all ascendant demographic groups and a favorable electoral map in 2010 are going to lead to more Democratic gains. A worse offense is the contempt for one’s readers’ intelligence that would be a necessary condition for writing stories about a Republican comeback when literally no polls point to such a trend. Show us where the public’s skepticism about policy details is translating into improved numbers for Republicans.

Rasmussen seems to generate polls to encourage Republicans than ones that are accurate.

Rasmussen is generally regarded as the most reliable pollster in the country. No one, absolutely no one, questioned their veracity when they showed Obama doing well. And all of the other major polls–if differing in intensity–show pretty much the same direction.

Even when they showed Obama doing well, they showed him less well than the other polls.

During one downturn for Obama in 2008. Rasmussen himself was on Hannity talking about how bad Obama was doing in the polls. The very next morning Obama was up in the Rasmussen poll (something Rasmussen would have known the night before). Instead, Rasmussen shamelessly promoted Obama’s weaknesses in a poll that was outdated.

You’ll also find ads for Republicans rather than Democrats on Rasmussen’s site.

I’ve found them to be reliably biased.
