The general election is being described as the most web-friendly yet, but the big change for this round is the addition of US-style televised debates.
Although the action will be taking place on TV, the debate is expected to kick off online, as people turn to social networking to instantly pick apart every point made.
Conversation will surely take off on Twitter, as it has for highly charged political television like the Question Time with BNP Leader Nick Griffin.
But the other social networks and sites are also looking to draw some attention.
Google has set up a dedicated General Election 2010 page, which charts the number of searches for the leaders, chancellors and parties.
Google is also keeping an eye on topics, with the NHS, education and taxes well outranking the wars in Iraq and Afghanistan, today and over the past month.
For tonight's debate, Facebook has set up a Democracy UK page.
"This application allows you to give instant feedback on the televised prime ministerial debates as they happen. Use the application to rate the debates while you are watching them live on TV," the page says.
YouTube is getting in on the action as well, letting users post a question to the party leaders in video form as part of their "Digital Debate".
"Put your questions to the party leaders and vote on other people's by clicking thumbs up and thumbs down," the site explains. "The week before the election, the leaders will post video answers to the most popular questions across the five categories."
