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.
The historical pattern of a state's voting has relevance to the upcoming election. Political culture does not change overnight, and Republicans will be counting the vote.
I was in Texas as it went from D to R, and I can show you the signs. Republicans started winning offices that they just did not win until then (John Tower, Bill Clements), and although the older and more established incumbents kept winning, their intended successors lost to newer Republicans. Some pols (Phil Graham, Ralph Hall) went from D to R, which was especially true in judicial races.
It is not bias; it is the expectation of inertia, ordinarily a reasonable assumption.
