Marriage Polls: Christian Miracles

David Cameron’s plans to introduce same-sex marriage could have cost the Tories the support of millions of churchgoers, polling suggests. 

Almost six out of 10 people who attend services regularly say they are less likely to vote Conservative at the next election because of the plans to redefine marriage.

More than a third of those polled said it had no effect on whether they would support the Conservatives but most of them would never vote for the party anyway...

Daily Telegraph. 

But of course this is in the serial gay marriage bashing Telegraph. 
Can you guess who's behind this poll? 
Yup, it's the evangelical Christian fruitloops at Coalition4Marriage.
And it was conducted by ComRes, who've also conducted marriage polls for the Christian Institute and Catholic Voices. 
Here's why they were both discredited by using dubious methods/questions - and, as if by magic, produced results that showed support for gay marriage at about half that of other polls.
How do they do it?
