George Allen is best known as former Virginia governor and senator who is now running for the U.S. Senate seat that he lost in 2006. His likely opponent will be Tim Kaine, former Virginia governor and DNC chairman. Both have extensive knowledge in political circles ... both have extensive means to raise the piles of cash necessary to run such a high profile race.
Allen has opponents for the Republican primary. They may not like the fact they have pretty much been written off by the national media who see two titans going against each other as the race-to-watch in November 2012.
In other words, if there's to be a battle with Tim Kaine, there needs to be someone who can actually win against him. Ken Falkenstein at Bearing Drift offers more.
