U.S. Sen. Ted Cruz emerges victorious at a rally Monday, February 1, in Des Moines after taking first place in Iowa's Republican caucuses on Monday, February 1. With about 99% of precincts reporting, Cruz had 28% of the vote, compared with 24% for Donald Trump and 23% for U.S. Sen. Marco Rubio. "Iowa has sent notice that the Republican nominee and the next president of the United States will not be chosen by the media, will not be chosen by the Washington establishment," Cruz said.
With former President Bill Clinton and daughter Chelsea at her side, Democratic presidential candidate Hillary Clinton addresses supporters February 1 at Drake University in Des Moines. The following morning, the Clinton campaign declared victory in the razor-thin contest against Sen. U.S. Bernie Sanders. "Hillary Clinton has won the Iowa caucus," the Clinton campaign said. "After thorough reporting -- and analysis -- of results, there is no uncertainty and Secretary Clinton has clearly won the most national and state delegates." The Iowa Democratic Party indicated in a separate statement it was not ready to make a call.

"Nine months ago, we came to this beautiful state, we had no political organization, we had no money, we had no name recognition and we were taking on the most powerful political organization in the United States of America," Sanders said. "And tonight, while the results are still not known, it looks like we are in a virtual tie."

Rubio addresses his supporters at a caucus night rally in Des Moines. "This is the moment they said would never happen," Rubio said. "For months, they told us we had no chance. They told me that I needed to wait my turn, that I needed to wait in line. But tonight here in Iowa, the people of this great state have sent a very clear message: after seven years of Barack Obama, we are not waiting any longer to take our country back."
