Political forecasts from Split, by outspoken Europeans (4,5)

I believe the answer is:

exit polls

I'm a little stuck... Click here to teach me more about this clue!

'political forecasts' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'split by outspoken europeans' is the wordplay.
'split' becomes 'exit' (I've seen this in another clue).
'by outspoken europeans' becomes 'polls' (I can't justify this - if you can you should give a lot more credence to this answer).
'exit'+'polls'='EXIT POLLS'

'from' acts as a link.

Can you help me to learn more?

I've seen this clue in The Sunday Times and The Times.
