As one person said to me , Republicans know [Donald] Trump is a stain on their party.

Hillary Clinton is also not a very exciting, inspiring candidate to a lot of the left-leaning Democratic base, especially in Iowa.

There was another Cleveland rally [of Hillary Clinton] - this one with LeBron James.

As those states and others in the South and West become more diverse and educated, they will become harder for the Republican Party - in its current form - to win.

The president is under 50 percent approval ratings in all the battleground states. So, you could say that President Obama is defying gravity by still being in a dead heat with Mitt Romney. And one of the reasons that he is, is because the changing face of the electorate are giving him a small boost.

Republican voters are coalescing behind [Donald] Trump, but many Republican elected officials still say they can't support him.

If [Hillary] Clinton can't boost African-American turnout, even with all that help, the question becomes whether she can make up for it with historic levels of support from Hispanics and suburban women.
