Is "Dudaba que" always followed by the subjunctive?

Question

Which of these is correct? Or are both acceptable?

Dudaba que fueran a terminar a tiempo...

Dudaban que iban a terminar a tiempo...

Thank you!

Answer 1

Hi silver, yes , always followed by subjunctive

Thanks Heidita: it seems that a lot of native Spanish speakers struggle with the subjunctive too! - silverlake, Jul 5, 2010
