Now that the presumptive nominees have been picked for the Republican and Democratic parties, a general election strategy is beginning to emerge for both parties.

On Wednesday Sen. John McCain sent a letter to Sen. Barack Obama inviting him to participate in a series of 10 town hall meetings before the Democratic National Convention in August.

"I propose these town hall meetings be as free from the regimented trappings, rules and spectacle of formal debates as possible," McCain wrote. "And that we pledge to the American people we will not allow the idea to die on the negotiation table as our campaigns work out the details."

According to The Associated Press, an advisor to Obama's campaign said the Democrat is receptive to the idea.

The source also said the Obama campaign would like to see exchanges that are structured more like the historic Lincoln-Douglas debates.

McCain proposes that the town halls include up to 400 audience members, be between 60-90 minutes long. He would also like the audience to ask the questions.
