Occasionally they will attempt a weak attempt of rebuttal by parroting some Obama lie like “jobs created” but they have to be embarrassed by the factual jobs lost and higher unemployment rate.
Except when liberals see they are wrong, they dont change their views and try to get it right, they project on the other side, try to hide the facts, and try to destroy their opposition. If that doesnt work they would tear down the whole society rather than admit error (see Wisconsin)
