By CNN's Jack Cafferty:

Europe's financial crisis is a warning siren for the U.S., but many Americans aren't listening.

A new Gallup Poll shows only 16% of those surveyed say they're following the news about Europe's crisis "very closely."

33% say "somewhat closely," 21% say "not too closely" and 29% "not at all."

This poll also shows even though all Americans aren't paying attention, 71% are concerned about the impact of the European financial crisis on our economy - that includes 31% who are very concerned.

It's been suggested that Americans' concerns about Europe might be higher if more people were actually paying attention.

And it's too bad they're not.

What's going on in Europe is a big part of the reason why we've seen such recent volatility in U.S. markets.

And if it continues, we could see a drop in U.S. exports and less European investment in the U.S. Also, U.S. banks could decrease lending here at home due to worries about Europe.

Meanwhile things are going from bad to worse in Europe. on top of concerns about Greece's debt crisis, Spain is dealing with a huge banking crisis.

Many of Spain's large banks are crippled by bad debt and money is fleeing the country in massive amounts.

Portugal, Ireland and of course Greece have already had to seek international bailouts due to high borrowing costs by the government.

But in the case of Greece, the citizens made it very clear in the last election they are not interested in the government spending less money. They want their handouts come hell or high water. Sound familiar?

Oh, and our government isn't paying attention either. Many of the things leading Europe deeper into crisis are running rampant here - and Washington does nothing.

Here’s my question to you: Most Americans aren't too focused on Europe's financial crisis. Should we be?
