Bernie Sanders this week launched a new campaign ad in which we hear the Senator speak some Spanish at the end.

While saying “Soy Bernie Sanders y apruebo este mensaje” is not a very difficult thing to say and have him practice, Bernie’s Hispanic campaign — and Bernie’s supporters — would be well advised to take a better look at their Spanish-language print and online copy.

Take the above promo by a Bernie Sanders advocacy group, which perfectly shows what many non-native Spanish speakers have known for years: The Spanish subjunctive is a bitch.

Oh… and DON’T get me started on “Progresivo” por favor.

UPDATE: This blog post was updated on Sunday February 21, 2016 to reflect the promo is not an official Bernie Sanders ad, but one created by advocacy group Women for Bernie.
