El voto nulo no apoya ninguna candidatura ni ningún partido político.

El voto nulo is being used in a general, category-level way. Spanish often uses the definite article to talk about something as a concept or type:

• El voto nulo = invalid voting / the invalid vote as a category
• Un voto nulo = one invalid vote

So here, el does not mean one specific ballot. It means the concept of a null/invalid vote in general.

In Spanish election vocabulary, voto nulo means an invalid ballot.

In Spain, this usually refers to a ballot that cannot be counted as a valid vote, for example because:

• it was filled in incorrectly
• it includes extra writing or marks
• it contains more than one ballot when that is not allowed
• it has some other irregularity

This is different from voto en blanco, which is a blank vote. A blank vote is valid, but it does not support any list. A voto nulo is simply not counted as a valid vote.

Because the subject is singular: El voto nulo.

• El voto nulo = singular
• apoya = third person singular of apoyar

So the sentence is structured like:

• El voto nulo = subject
• no apoya = verb
• ninguna candidatura ni ningún partido político = objects

If the subject were plural, the verb would also be plural:

• Los votos nulos no apoyan...

Because ninguno/ninguna must agree with the noun it modifies:

• candidatura is feminine singular → ninguna candidatura
• partido is masculine singular → ningún partido político

Also, ninguno becomes ningún before a masculine singular noun:

• ninguno
  • partido → ningún partido

This is the same pattern as:

• ninguna casa
• ningún libro

Yes, and that is normal in Spanish.

Spanish commonly uses double negatives, unlike standard English. Here:

• no apoya = does not support
• ni ningún partido político = nor any political party

So no ... ni ... is the natural Spanish structure for not ... nor ...

Examples:

• No come carne ni pescado.
• No llamó ni escribió.

In English, we avoid stacking negatives in the same way, but in Spanish this is completely standard.

Because ni is the natural conjunction after a negative statement.

• o means or
• ni means nor / not even / and not

Since the sentence already has no, Spanish prefers:

• no ... ni ...

So:

• no apoya ninguna candidatura ni ningún partido político

sounds much more natural than using o here.

Not exactly.

In this context, candidatura usually means a candidacy, electoral list, or slate of candidates, depending on the election system.

It is not usually the same as one individual candidate. For one person, Spanish would more often use:

• candidato / candidata

So:

• ninguna candidatura = no electoral list / no candidacy
• ningún partido político = no political party

Because apoyar is a direct transitive verb, and these objects are being treated as things/institutions, not people.

So Spanish normally says:

• apoyar una candidatura
• apoyar un partido
• apoyar una idea

No personal a is needed here.

You are more likely to see a when the object is a specific person:

• Apoya a María.
• Apoyan al candidato.

But with candidatura and partido político, leaving out a is normal.

Because in Spanish, descriptive adjectives usually come after the noun.

So:

• partido político = political party

This is the standard noun + adjective order.

Placing the adjective before the noun is sometimes possible in Spanish, but it often changes the tone or sounds unnatural. In this case, político partido would not be the normal expression.

Yes, that would be grammatically possible, but it would mean something slightly different in style.

The original sentence uses:

• ninguna candidatura
• ningún partido político

This is very explicit and clear: not any candidacy and not any political party.

A version without ningún/ninguna could sound more general or less emphatic in some contexts. The original is more precise and is especially natural in explanatory or formal language.

Yes. In Spanish, most adjectives normally come after the noun, especially when they classify or describe it in a straightforward way.

So:

• voto nulo = invalid vote
• partido político = political party

This is the most neutral and standard order. Putting nulo before the noun would sound unusual here and would not be the normal way to express this idea.

Apoya is the present indicative form of apoyar.

It is used here because the sentence states a general fact or definition, not something happening only at one specific moment.

Spanish often uses the present tense for general truths, rules, and definitions:

• El agua hierve a 100 grados.
• Un voto nulo no apoya ninguna candidatura.

So here the present means something like by definition / in general.

Because the stress falls on the syllable lí: po-LÍ-ti-co.

Without the accent, Spanish stress rules would make it sound different. The written accent shows the correct pronunciation.

This is just a spelling rule:

• político
• económico
• público

They are all stressed on the third-to-last syllable, so they need a written accent.
