Verb Tense Trouble

For some reason, a whole lot of people here use the subjunctive tense when they are supposed to use the conditional. I don't remember this being the case before. Perhaps it's just a recent trend. I've heard politicians and news casters do it on TV. It drives me crazy! For example, someone will say "Debiéramos ir al cine" instead of "deberíamos ir al cine." I even caught my dad doing it the other day.
