Hillary Clinton is back in the race to become the Democratic presidential candidate, and it's perfectly clear that Jack Nicholson deserves all the thanks.

Look at the evidence. Hillary Clinton is behind in the polls and then - bam! - Jack Nicholson makes an incomprehensible video where some of his nastiest screen characters sort of vaguely say lines of dialogue that might possibly be construed as endorsing her and she wins big in three important states.

And now, just to mop up all the praise that a befuddled-looking Father Jack-esque appearance on a woolly political YouTube video deserves, Jack Nicholson has given an interview all about how he's the world's bestest ever at politics and stuff. 

This could be Hillary Clinton's last week of trying to be the next American president, so now's the time to bring out the big guns.

Well, alright - not the big guns exactly. But at least the elderly, debauched, paunchy guns have been wheeled out. And by that we plainly mean Jack Nicholson. 

Ahead of this week's vital Ohio and Texas primaries, Jack Nicholson has put together a campaign video of him in some of his most famous roles to drum up support for Hillary Clinton. And we're sure Jack's pro-Hillary message will get through to the two or three people who saw it and didn't cack themselves at the sight of the drunk-looking, growling, dishevelled jowl-monster who pops up at the end like the obese ghost of your abusive grandfather.

Hindsight's a bitch - it's easy to wonder how different things would be if Hitler got more hugs or someone said "No Jamie Lynn, not without a condom."

But someone who has no time for hindsight is Jack Nicholson. Though it's natural for people close to Heath Ledger to ask themselves if they could have done anything differently to stop his death, Jack Nicholson doesn't have to.

That's because Jack Nicholson says he warned Heath Ledger about taking sleeping pills. And if things are bad enough for Jack Nicholson to warn you about stuff...
