Sen. Ted Cruz scored a hard-fought upset win over businessman Donald Trump in the Iowa Republican caucuses Monday night, making good on his bet that a methodical campaign organization would eclipse the New Yorker’s media dominance in the first test of GOP voters. On the Democratic side, former secretary of state Hillary Clinton and Sen. Bernie Sanders (I-Vt.) were virtually deadlocked with 93 percent of the precincts reporting. Clinton had been a clear front-runner last summer, but Sanders narrowed the margin in Iowa into a dead heat in the final days, and he maintains a polling advantage in New Hampshire, which will hold its primaries next week.
