GOP disapproval rating

The regressives keep making a big deal out of President Obama's 54% disapproval rating. True, it's not good. But the GOP's disapproval rating is 72%. The Democrats fare only slightly better at 61%. And yet polls show the "public trusts Republicans more than Democrats on the economy, spending, foreign policy and immigration." Based on what evidence? There is no evidence to support such trust. I guess it's true that these folks are falling for the framing manipulation instead of actually informing themselves on the facts and issues. Which of course is exactly what the regressives want, since they could in no way get such support based on evidence.
