Travis County, TX? Biden got 71%, yet Bush actually won it in 2000. (Granted, with a plurality thanks to Nader’s strong showing, but Bush still got 47%, a lot more than what Trump received.)
Travis County went from a population of 800k in 2000 and 1.3M in 2020, and the demographics of people moving to Austin skews very liberal.
Trump's 2020 performance in Travis County is actually a record for the Republicans, 161k votes, compared to Bush's 141k in 2000. But when you compare Biden and Gore, it's not even close. Gore got 125k votes. Biden got
436k.Bush-Biden voters certainly exist in Travis County, but much less than seems at first glance. More an influx of Democrats than flipping of Republicans.
