After employing images of a "Chair" (subscription) and a "Storm" (subscription) to question Barack Obama's ability to lead in uncertain times, the Republican National Committee is once again using vivid symbolism to lambaste the Democrat, in a new ad released this morning.

"Surgeon" (subscription), the final installment of what RNC spokesman Brad Todd says is the party's "closing argument," begins with an announcer asking, in a grave tone: "Would you get on a plane with a pilot who has never flown? Would you trust your child with someone who has never cared for children? Would you go under with a surgeon who has never operated?" The ad then draws a parallel between these scenarios and the prospect of an Obama presidency, citing a quote from the Irish Sunday Independent: "Can you hand your nation to a man who has 'never been in charge of anything?' Can you wait while he learns?"

The original quote, published in mid-September, was actually targeted at Joe Biden: "Obama chose a charisma-free windbag who is the archetypal Washington insider and -- like Hillary [Rodham Clinton] and Obama himself -- has never been in charge of anything."

"Surgeon" is running in Ohio, Indiana, Florida and Virginia, which are among the same handful of battlegrounds where John McCain is focusing his ad dollars as well.

The RNC also released a Spanish version of "Storm" today in the Miami and Fort Lauderdale, Fla., markets. This pivotal state, which was lining up solidly in the McCain column until mid-September, is now leaning toward Obama by at least a handful of percentage points in various national polls, according to Pollster.com.

The RNC is wrapping up its on-air efforts in Colorado, Pennsylvania and the once-solid red states of West Virginia, Montana and North Carolina as well. According to a press release, the party is in the process of spending more than $25 million in the last two weeks leading up to Nov. 4.
