Continuous coverage was reported by bloggers all over the country. Most notable was CNN's Blog Party in Washington DC. Bloggers from Wonkette, MyDD, RedState, The Huffington Post, and several others spent the evening posting about election results and their potential impact on the race for the control of Congress.

Citizen journalism was also big this year. Voters all over the country documented their Election Day experiences. They reported machine problems, insufficient numbers of machines and lines so long that people were leaving before they voted. Then they posted those videos on YouTube. Examples: Veek the Vote and Video the Vote.

And although news outlets have always provided graphics to show the winners, this year marked some pretty fancy features. Nearly every news outlet had an interactive graph or a map that allowed users to track gains in the Senate, House, and gubernatorial elections.
Some good examples are Google Earth Election 2006 Layer, New York Times Election 2006 Map, 
 CNN America Votes 2006 and The Wall Street Journal Interactive.

This year also marks the most content available to voters online. Numerous websites were dedicated to helping voters make it to the polls, learn about candidates and educate themselves on issues.

Regardless of the outcome, which--in case you have been living under a rock--ended with the biggest Democratic gain since 1980, the Internet has proven its usefulness when it comes to politics.
