In the Web 2.0 race for the US White House, Senator Barack Obama continues to dominate rival Senator John McCain in several areas.

At the time of the Iowa Democratic caucus in January this year - which Barack Obama went on to win - he led the entire presidential pack in the Web 2.0 world with the most Facebook friends, MySpace friends and YouTube views.

On the Republican side, Ron Paul and Mike Huckabee - the Republican victor in the Iowa caucuses - were the top Web 2.0 candidates with 88,000 and 7,000 supporters respectively on MeetUp, a site that helps supporters organise in-person activities for to rally for candidates.

In the current online race, Obama continues to dominate. On Oct. 21, for example, Obama raked in more than 84 million views for his YouTube videos while JohnMcCain posted 22 million, according to TechPresident, a site that charts Web 2.0 election statistics. Over the past six months, 13,702 Meetup members have used the site to organise offline groups and events to support Obama, while 1,472 members are using it to rally around McCain.

For the seven days ending Oct. 22, Obama was mentioned 10, 291 times in the blogosphere, according to Technorati - which tracks blogs - compared to 3,924 mentions for McCain.

And Hitwise - which tracks web traffic - noted that Obama was pulling in 67% of all web traffic directed to presidential candidate sites while McCain was pulling in 32% of that traffic.

Obama has also continued to dominate on Facebook, with 2 million Facebook supporters on Oct. 9, compared to McCain's 564,000. The Democratic candidate also leads on MySpace, with 749,000 supporters as of yesterday, compared to McCain's 190,000.

Both candidates have leaned heavily on the internet during the run-up to election day with recent moves including Obama's launch of an iPhone application and McCain's move to query users on professional social networking tool LinkedIn and to overhaul his "McCainSpace" MySpace page.

In the days leading up to the Democratic National Convention in August, McCain had a strong online surge - especially in the blogosphere that had long been Obama's stronghold.
