Why wasn't the contraction I'll accepted?
We vote "at" an election as well as "in" an election.
Totally agree. I would commonly us ‘at’ rather the ‘in’. Both should be acceptable.
'I will be able to vote next election' is also common usage, at least in the UK
Duo accepts 'at'.
Je pourrais sounds similar with je pourrai.
Would say at the next election in UK English
Im losing my hearts
Does Duo accept 'I will be allowed to vote in the next election' too ?
