Ah, I see. This may be your first primary.
unlike the general, the primary goes in waves, sorta- with the first states in Feb (Iowa, New Hampshire, Nevada, South Carolina) being the most important, followed by a slew of super tuesday states on March 1st (AL, ,AK, AR, CO, GA, MA, MN, OK, TN, TX, VT, VA) generally putting the nail in the coffins of straggling campaigns.
Everything after this is basically irrelevant. whoever is the frontrunner by the time the first states are done and possibly super tuesday hits will have an insurmountable lead- volunteers and funding tend to dry up as losses and wins rack up.
it NEVER goes all the way to the final tier of states- those are virtually always irrelevant. Rubio doesn't have till august to unseat carson and trump, he has until February.
