Despite what thethe spouts, Trump is not a well liked candidate among traditional Republicans/conservatives (which make up a ton of TX and FL voters). But neither state is remotely close to turning blue. Particularly TX, where Biden's border policy has pissed off almost every single Texan, regardless of party. Currently Trump is polling 8 points ahead of Biden, and has been polling 8-11 points better than Biden all year. In 2020 he beat Biden by 5.5 points despite only leading by 2-3% in the pre-election polls.
GA went blue one election, which can largely be attributed to COVID. Trump had a comfortable lead in the polls prior to COVID, then slowly Biden took over as the year went on. Currently, Trump has a 5 point advantage in GA and has had a 5+ point advantage all year. Aside from Democrat shenanigans and an October surprise, GA is a lock for Trump and it won't be particularly close. Probably will win by over 200k votes
The main state that has turned purple is North Carolina. It's a state that has been decided by 3 points or less every election since 2008. Conversely though, Trump has managed to turn Iowa and Ohio to deep red states, instead of the swing states they were for the prior 20-30 years.
