El programa electoral llegó a cada circunscripción durante la campaña electoral.

In Spain, programa electoral usually means an election manifesto or policy platform: the set of proposals a party presents before an election.

A learner might expect programa to mean only TV programme or computer program, but in politics it commonly means manifesto / platform.

Circunscripción is a political or electoral district, often translated as constituency in British English.

In Spain, it refers to the geographical area used for elections. So cada circunscripción means each electoral district / each constituency.

Because the verb llegar normally uses the preposition a before a destination:

• llegar a Madrid
• llegar al pueblo
• llegar a cada circunscripción

So a here means to in the sense of movement toward a place.

Llegó is the pretérito indefinido (simple past) of llegar, third person singular.

It is used here because the sentence presents the action as a completed event in the past: the manifesto reached / arrived at each constituency during the campaign.

A learner might compare:

• llegó = it arrived / it reached
• llegaba = it was arriving / it used to arrive

So llegó fits better if the sentence is describing a finished fact.

Yes. Literally, llegar often means to arrive, but in many contexts English will translate it more naturally as to reach.

So this sentence could sound like:

• The election manifesto arrived in each constituency...
• The election manifesto reached each constituency...

The second version is often more natural in English if the focus is on distribution rather than physical arrival.

Cada means each, while todas las means all the.

• a cada circunscripción = to each constituency, one by one / individually
• a todas las circunscripciones = to all the constituencies

Both are possible in principle, but cada emphasizes every individual district within the whole set.

Also, after cada, the noun stays singular:

• cada circunscripción not
• cada circunscripciones

Because electoral is modifying two different nouns:

• programa electoral = election manifesto
• campaña electoral = election campaign

Even though the same adjective appears twice, this is completely normal Spanish. It is not considered awkward in the same way repetition sometimes can be in English.

Also, electoral does not change form here because adjectives ending in -al usually have the same masculine and feminine singular form:

• programa electoral (masculine singular)
• campaña electoral (feminine singular)

Spanish uses definite articles more often than English.

Here, El programa electoral and la campaña electoral refer to specific, identifiable things in context:

• the election manifesto
• the election campaign

Spanish often includes the article where English might sometimes omit it, especially when talking about a known event, object, or situation.

Yes. Spanish word order is fairly flexible, especially with time phrases like durante la campaña electoral.

For example, you could also say:

• Durante la campaña electoral, el programa electoral llegó a cada circunscripción.

This puts more emphasis on the time frame. The original version is perfectly natural too.

Yes. Durante directly means during and is very natural in this sentence:

• durante la campaña electoral = during the election campaign

A learner might wonder about en, but en la campaña electoral would not express the same idea as clearly here. Durante specifically marks that the action happened within that period of time.

A few useful points:

• llegó has stress on the last syllable because of the written accent: lle-GÓ
• circunscripción also has stress on the last syllable: cir-cuns-crip-CIÓN

For Spain Spanish pronunciation:

• ll is usually pronounced like y in much of Spain today
• ci in circunscripción is pronounced with a th sound in most of Spain: roughly thir-cuns-crip-ción

So an approximate Spain pronunciation would be:

• ye-GÓ
• thir-cuns-crip-THYON or thir-cuns-crip-SYON, depending on the speaker

Yes, it sounds fairly formal and political because of words like:

• programa electoral
• circunscripción
• campaña electoral

These are common in news reports, political analysis, and official discussion. In everyday conversation, a speaker might sometimes choose simpler wording, but this sentence is perfectly normal in a political context.
