Should we move to public financing of elections, or continue the system as it exists today?

I assume that you are talking about the United States.  If
so, I would argue that we should not move to public
financing.

I understand that public financing would seem
fairer.  If candidates had only a certain amount to spend, the richer candidates would
not have an advantage over those with less money.

However,
I think that Americans do have the right to use their money to promote their political
beliefs.  Therefore, I do not think the government ought to be able to limit how much
money someone can spend on airing their political views.  If we allow people to spend as
much as they like on this, there is no point in public financing because people would
just get around these limits by making "issue" ads that are really for or against some
candidate.
