The poll also found that over half, 56 per cent, had visited political websites to learn more about the parties they could vote for.
The survey was conducted to gauge public perceptions and attitudes towards the use of social and digital media by the leading political parties.
Eb Adeyeri, Digital PR Director at Lewis PR, said: 'Many commentators believe this will be the UK's first 'internet election' with politicians exploiting channels such as Facebook and Twitter to convey their message. Online campaigns are measurable, are a great way to engage people in real-time and are clearly going to feature prominently in this election.'
24 per cent of those asked believed that Twitter was an essential communication tool in a democracy.
The survey polled 1,000 members of the public.
