While Democrats seems to be wringing their hands over Sarah Palin's popularity, Barack Obama suddenly took a 47-45 percent Gallup Poll lead over John McCain on Wednesday.

That means Obama has wiped out McCain's five-point lead of just a few days ago.

Bad U.S. economic news -- all occurring under the watch of a GOP president -- clearly is weighing on McCain's campaign.

As the Gallup pollsters said: "There is thus a correlation between the bad financial news and Obama's gains....

"Throughout the campaign, Obama has generally held an edge over McCain when voters are asked who could best handle the U.S. economy, although McCain gained on the economic dimension in polling conducted immediately after the GOP convention."

However, I'm not sure even Obama wants a continued, steady drumbeat of negative economic developments the next seven weeks.

That might mean he would be elected, but to lead a country in financial peril.
