The [Hillary] Clinton campaign's recent travel schedule shows how seriously it takes this problem. She and her surrogates have held rallies in cities like Philadelphia, Detroit and Cleveland, trying to boost turnout among African-Americans.

If the Congress is going to spend its whole time hauling up regulators and bureaucrats and looking like they're focusing on tiny, trivial things, instead of jobs and the economy, it could be a problem for them.

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

Obama has built his public image around his ability to bridge divisions - racial, ideological or generational. And that was his reputation, even at Harvard Law School, where he was the first black president of the 'Law Review.

[Hillary] Clinton has also struggled with key groups of voters.
