This post is part of a series in which TheStockAdvisors.com asked financial experts to name their top stock pick if McCain or if Obama wins the election.

"The GOP is traditionally known as the party that spends more on defense; thus, if McCain wins the election, one stock to benefit would be defense firm General Dynamics (NYSE: GD)," says John Reese, editor of Validea, which follows the strategies of "legendary" investors such as Warren Buffett and Peter Lynch.

"While McCain has talked tough about reforming the defense budget, he has also pledged to increase the size of the military, modernize the armed services, and push hard for strong missile defense systems -- all of which require serious spending.

"As a major producer of battle tanks and assault vehicles, armaments and munitions, battleships and nuclear submarines, and military information technology systems, this Virginia-based firm is thus likely to have quite a bit of work on its hands during a McCain presidency.

"Just as importantly, General Dynamics' finances and fundamentals are very strong, earning approval from both my Peter Lynch and Warren Buffett-based Guru Strategies -- computer models that are each based on the approach of a different investing great.

"Because of its moderate 18.14% long-term growth rate and huge annual sales of $28.7 billion, General Dynamics is considered a 'stalwart' by my Lynch strategy, the type of large, steady firm that Lynch found offered protection during downturns or recessions.

"Two big reasons my Lynch model is high on this stalwart: its yield-adjusted P/E/Growth ratio of 0.75, which signals that the stock is a bargain right now, and its 18.79% debt/equity ratio, a sign that GD has the conservative financing Lynch liked to see."

My Buffett-based model, meanwhile, likes General Dynamics' consistency. Over the past decade, its EPS have declined just once, rising from $1.46 to $5.10 in that time.

"The company's annual return on equity -- a figure Buffett used to find firms with the 'durable competitive advantage' he famously prizes -- has been at least 16.4% every year.

"GD has also retained $22.30 in per-share earnings in the past decade while increasing EPS by $3.64, showing it can earn investors a 16.3% return on the earnings it keeps. That's a sign of the strong management Buffett is also known to look for."
