It shouldn't be. Most of the people who went from Spain overseas was from Andalucia, the South American accent came from the Southern Spain. Also, lots of spelling traits in Southern English from the US map 1:1 to Andalusian Spanish, such as omiting vowels between consonants and speaking really fast.

I am not sure if that is true (it might be).

In Argentina they call spaniards gallegos, like from Galicia, the Spanish region north of Portugal.

Do you have an example of omiting vowels between consonants? IMO the whole Spain speaks quite fast.

Ah, sorry, I guess I was droopy. I meant consonant between vowels:

Reventado -> Reventao Colocado -> Colocao

On vowels between consonants, maybe "tarántula" -> Trántula spelling it really fast in a hurry.

But what I meant with the Andalusian accent being really fast and omiting vowels, they do in a way pretty close to the Southern US English accent.

Also, the Andalusians got a lot of arabisms (more than former Spanish) such as zaguán, babuchas, alcancía, alhaja, alcoba... the same way the Southern US English got lots of borrowings from Spanish.

Thanks for the examples. You make some interesting points. Also the arab influence of course makes sense in Andalucía.
