The first issue of race effecting polls is the Bradley effect and the reverse Bradley effect. The Bradley effect, as it is called, is a way to describe how when an African-American is running against a white opponent, the poll numbers sometimes do not match the actual vote totals. Basically it is hypothesized that white voters say they will vote for the African-American candidate or that they are undecided and then vote for the white candidate which was their intention all along. Some say this might be because white voters fell uneasy answering the question of who they will vote for because it might be seen as a racial decision. To avoid the appearance of racism these voters say they will vote for the African-American candidate or say they are undecided, when they have already made up their mind to vote for the white candidate, just to avoid the question. The reverse Bradley effect is used to explain why some African-American candidates poll lower and then get more votes in the final election. This hypothesis is based on the idea that pollsters are not polling enough African-Americans or young voters.
There are some who believe in the Bradley effect(Fred Barnes), some that do not(McCamy Taylor), and some that do but think it is no longer relevant such as Nate Silver and Dan Hopkins.
