The fact that Georgia and Texas are still rated Leans R despite Biden leading most polls while Biden pretty much has to pull double digit leads for the pundits to consider a state Lean D really show how biased prognosticators are to Trump.
They're being cautious, understandably so after massively underestimating Trump and humiliating themselves last time. However if nothing shifts soon I imagine they'll be moved to 'tossup' (Georgia before Texas). I wouldn't be surprised if Georgia is projected as Lean D by election day though I imagine they'll chicken out on Texas and move it back to Lean R (if they eliminate tossups that is).
