Seems to me that whether or not your claim is true and whether it is something that reflects poorly on Obama is a matter of what you are actually measuring.
My statement is directly in context with the question posed to the audience in regard to personal experience.
Do you have any interesting links to threads on the net where someone has raised this issue and people have refused to believe that so we can see if it looks like it is bias that is at work rather than a disagreement over 'real' terms, % of GDP, or if they are bickering as to who is to blame for that occurring?
The question was raised from a personal perspective. I don't know how the average "leftist" would respond.
The thing we won't be able to do is to see if the people you are talking about 'backfire' regarding the position or whether or not they simply disregard the correction since it is that phenomenon which the study is is addressing: and it is not something that can be detected without a great deal of care.
I agree, which leads me to question 1. What the political persuasion of the experimenters is and 2. What the purpose of the experiment is.
I personally have seen much cognitive dissonance coming from the Right to include the most ridiculous instances of protective Bush (which really is them trying to save face for backing him). That is not in question. The question is why this wouldn't apply to the other foot.
