GORHAM, N.H. — Former Florida Gov. Jeb Bush says Republicans won't win the White House if candidates don't campaign in "every nook and cranny" of the country, especially in Latino and African-American communities.

The Republican presidential contender made his comments Thursday during a town hall meeting in New Hampshire. They come as businessman Donald Trump's hardline rhetoric on immigration continues to dominate the GOP primary race.

Bush did not mention Trump by name during Thursday's appearance. He previously has said he is offended by Trump's description of Mexican immigrants as "rapists" and "criminals."

GOP officials have been working for years to broaden the party's appeal beyond older, white voters as the country's demographics change.
