Trump will bounce back, but it's Bernie Sanders who's sent shockwaves through this race.

There were many surprises in last night’s Iowa Caucus results.

Front-runner Donald Trump lost, which for a natural-born winner like him - on record as saying ‘nobody remembers the name of who came in second’ – is a big, though not terminal, blow to his presidential hopes.

Tea Party darling Ted Cruz won, proving he’s got a much better game-plan on the ground than many gave him credit, and has clearly sewn up the crucial evangelical base.

Marco Rubio came third but may as well have won given the massive significance of him blowing away all his ‘moderate’ Republican rivals like Jeb Bush and Chris Christie. (Expect a ton of GOP cash flooding to the young Hispanic senator now as the old establishment guard rush to back the only apparently viable alternative to the two untamed right-wing renegades, Trump or Cruz.)

But the real shock came in the Democrat contest.

Let’s remember where we were just a few months ago.

This was supposed to be a simple, virtually unopposed coronation of ‘Queen’ Hillary.

Once Vice-President Joe Biden ruled himself out, her ascension to the Democrat throne appeared to be a formality.

Oh, there was this barmy old guy called Bernie barking in the background, but nobody took him seriously. Least of all the Clintons, who must have viewed him as the perfect internal opponent.

If you’d told Hillary, or her husband Bill, this time last year that she’d struggle to beat a 74-year-old ‘independent socialist’ in the Iowa Caucus, they’d have laughed their heads off.

Well, any laughter’s long since stopped, and they’re taking that old guy called Bernie bloody seriously now.

As should everyone else.
