Word for a person who represents everyone

I'm looking for a word to fill in the following phrase on my school elections. "Foreign by birth. __________ for all." In the blank I was thinking "people's person", "representation for all".

I want a word that means a person who represents everyone and everyone's wishes.

Not anything like politician.

Solution 1:

Foreign by birth, Representative for all.

Seems least contentious; it implies a person's loyalty to the general civic interest. "Representative" here can be either a noun (one who represents on behalf of others) or an adjective (as in 'a representative sample'), or can be understood both ways.

Whereas "representation for all" suggests correcting for some perceived under-representation of minority interests.
