Kind of, but of course Franco wasn't a 'politician', he was a military dictator. Madrid wasn't by any means a Francoist city and the war for the nationalist forces to capture it was long and bloody.
Franco did have very centralist ideas with respect to his concept of "Spain" as a nation. As well as all the customary jingoism he imposed on the population, he also worked hard to crush regionalism, principally the basques & catalans*.
A big strong football team called Real Madrid, playing in white and dominating Spanish and European football (many successive European Cups) fitted in perfectly with his ideas, and so at boardroom level, every help & assistance was given to "Spain's club". This just made the fans of Bilbao, Barca, At. Madrid and all the rest hate them more. Safe in the knowledge that the administration (and often the refs) were in their favour, the Real fans developed that smug sense of entitlement and superiority which still marks them today.
When the catalan and basque languages were banned, the terraces of San Mames and Nou Cmap were two palces where there was sufficient safety in numbers to chant (often anti-franco) songs in their own language.
I don't think the players ever really had anything to do with it, but given that the situation was widely understood, then going to play for Real always had undeniable political undertones.
Despite the set up, Madrid's domination in the period 39 to 75 was far from complete.
During that time, the Spanish FA Cup was called the Copa del Generalissimo. This in itself was a fantastic motivation for a basque or catalan to try and win the Cup, just to watch the despicable midget's fce as he handed over the silverware.
* Although we tend to focus on those two regions, many many more people suffered as bad and much worse under the regime. The Canary islands crminally neglected by the mainland, the Galicians too (Ironic as Franco was gallego). Of course for anyone of less than firmly right wing, catholic, military tastes, times were permenantly grim.
Cheers - thanks for the detail.
And you're absolutely right - my choice of the word "politician" to describe Franco was a poor one.
