The next GOP President needs to win GA, WI, AZ, which Trump lost by a total of 43,000 votes in 2020.
That creates a 270-270 tie, which the Republican will win easily in the House of Reps, because each state only gets ONE vote.
Or, if we can win back one Electoral Vote in Nebraska CD #2, the Republican would win 271-269.
You are conflating “winning the next Presidential election” and “becoming the next President”.
