Answer:
Regulations cannot (or should not) hamper in any way freedom of speech
Explanation:
As (freedom of) speech forms part of the political campaign it cannot be subject to less/more stricter regulations.
Campaign finance regulations have no impact on political speech.
Any democratic country that takes itself seriously should try to protect freedom of speech more than regulations. Like Voltaire said: ¨I don´t agree with him (Rousseau) but I won´t deny his right of expression.¨
