US elections, minority candidates, and role models?
Is it true that any ethnic minority candidate who wishes to run for the US House of Representatives, the Senate, or the White House would, to some extent, be expected to act as a role model for his own group, and to act as a bridge between his own group and the mainstream, political, White majority?
Is this one of the "unwritten" rules of US elections and is it true that ethnic minority candidates are usually elected on the assumption they would satisfy such a criteria?
