Is There a Risk of Not Being Relevant in Politics?

A big risk of going into politics or policy in general would be that your career progresses but you're not specifically in one of the places that ends up having a say in how these things go. Are there any roles that you can take early on or what can you do to position yourself well so that you don't just get sidelined in the end? I think if you intend to work in politics then you have to be somewhat opportunistic about jobs and the ebb and flow of political opportunities. So for example, if one congressional committee is declining and it's relevance in terms of AI then one should consider about jumping ship towards somewhere that's more relevant.
