Some people write bloated books and long essays with skilful use of hooks, e.g. Jared Diamond; some others speak in long-drawn sentences with torrents of words, e.g. Noam Chomsky. It reminds me of a tactic politicians use to waste people's time. I came across this word before but I can't retrieve it from either memory or the internet.
Obfuscation may be the word you are looking for. It implies that a thing is being presented, but not necessarily in the most clear manner, often with the intent of deception on key details. That said, this may not be strictly political.
Somewhat related is the Gish gallop https://en.m.wikipedia.org/wiki/Gish_gallop where you do an 'argument dump' to overwhelm your opponent.
This is a bit of a long shot, but:

This makes me think you're referring to the filibuster. The filibuster is a procedural tool in which a politician will just keep talking and talking in order to prolong debate and prevent the bill from coming to a vote.
Nowadays though, in the US Senate, you don't need to actually talk to filibuster. The procedural filibuster allows politicians to just announce that they are going to filibuster, at which point it takes a super-majority of votes to override the filibuster. However, a recent rules change means that it only takes a normal majority of votes to override a filibuster of a non-judicial presidential nominee.
