Unless Trump succeeds in emulating his idol Putin and making himself president for life, the GOP will need a new candidate in 2024. My best guess is that you will see something of a generational divide at that time. On the one hand, you can expect Marco Rubio and Ted Cruz (Class of 2016) to come back and try again; on the other, there will be new faces, such as Tom Cotton, Josh Hawley, and Rick Scott, in the picture.
Which generation will prevail? I will be addressing this question from a variety of angles in a series of posts over the next day or two.
