The Caucus-Primary system for Presidential elections needs to be reformed, as it is clear that having Iowa and New Hampshire go first, with both being totally lacking in diversity, is not a system for the long term.
The argument could be that California and Texas should go first, as they are very diverse and together have about 20 percent of the national population.
Add states such as Wisconsin and Virginia, and that would be a good start toward a system that would be much more amenable to the promotion of racial and ethnic diversity in a nation that will be majority non white in a generation. Therefore, it would be more reflective of reality, and allow minority candidates a better chance to survival in the process.
It is sad that Kamala Harris, Julian Castro, and Cory Booker have been forced out of the Presidential race for the Democrats, due to lack of financial support. Hopefully, the future can be different.
