As predicted, Iowa caucuses surprised many. The results hurt two people the most: Donald Trump and Hillary Clinton. One of them lost the caucuses while the other won it by whiskers.

Trump and Clinton have strongly been promoted by several Republicans and Democrats as the frontrunners of the US Presidential Campaign 2016. Polls spoke in Trump’s favour. Experts believed it would be a cakewalk for Clinton. Nothing of that sort happened.

Trump’s damage came from two sides. First, he was emphatically beaten by Texas Senator Ted Cruz, who heavily banked on conservative voters. Second, Marco Rubio was dangerously close to Trump, which surprised many as well.

The Republican race may not be a two-way contest anymore. Maybe it never was. Rubio stands as strong as Trump, and Cruz is not far ahead.

Things are a bit different for Democratic candidates. Bernie Sanders, whose idea of “political revolution” has apparently inspired the youth, turned out to be much stronger than presumed.

According to Republican strategist Ron Bonjean, the race between Clinton and Sanders will continue to be this tough until the end. He says Sanders’ “left-wing vision” is quite similar to Barack Obama’s in 2008 – one that defeated Clinton.

“One regret Sanders may have is not going after the Clinton email scandal much earlier in the primary campaign,” Bonjean told Politico.

Bonjean says the Republican race will now be decided by discipline, savvy and infrastructure. Whoever has it the most will win it, he believes.

Trump, who always seems incredibly confident about his winning, looked unusually calm during his speech after the caucus. He talked about beating Democrats while thanking everyone who worked hard for his campaign in Iowa.

“I don’t know what’s going to happen with Hillary; she has other problems, maybe bigger than the problems she’s got, in terms of nominations.” Vox quoted Trump as saying. “But we’ve had so many different indications and polls that we beat her and we beat her reasonably.”
