Now, look at the GOP. Right now, they're where they were in 1964. Divided, tugged far to the right, too far to win. But, they do have some moderate voices who might emerge in 2020 as potential big names like Rubio and Jindal, for instance. They have a lot of young minds and voices for Conservatism as well.
Do you really call Jindal a moderate of all things? He is one of the most far right there is. Economically, he's the most far right by a long mile of any of the 23 presidential candidates who have been running this year (though Rand Paul is pretty far right there as well, especially on taxes). Socially, he's also one of the most far right of all the candidates (though not quite as far right as Huckabee). Cruz is more of an obstructionist (more than he is far right) who doesn't really care about policy like most other candidates, but mostly/only to secure that there will be no progress what so ever for the Democratic agenda. Thus, for me personally, candidates like Jindal and Huckabee (and Brownback in Kansas) are in many ways more far right than
even Ted Cruz.
