Cross-over rules doesn't apply

Alabama's new crossover voting ban - which prevents a person from casting a ballot in one party's primary and then participating in the other party's runoff - went into effect earlier this year. The limitation does not apply to the general election, however, and voters can cast a ballot for whichever candidate they choose, regardless of party or who they voted for in the primary or runoff.
