Next General Election Forecast If 1% Vote Climate

VoteClimate's Forecast For The Next General Election indicates that if VoteClimate can recruit 1% of the electorate in marginal seats, there are 66 seats where we can change which party wins.

1% of the electorate in 66 seats is just 50,000 voters!

We have a huge and historic opportunity to force a race to the top on climate policy
