Here's what's up on Tuesday's Squawk on the Street:
--Another big day of corporate reports. On the list - Pfizer, Duke Energy, NYSE Euronext and Molson Coors.
--We're also exploring what a debt downgrade would mean for stocks, treasuries and your money. Plus we'll get ahead of this week's jobs report due out Friday.
--That brings us to the Street Poll. The only thing that's really clear about the market right now is that the market has a lot on its mind. Two of the main things of course are the deficit and the data. We want to know which has you more worried... the deficit or the data? Share your opinion.
--And we'll get auto sales numbers. Toyota, General Motors and Ford will show us how they fared in July.
Squawk on the Street comes to you live from the New York Stock Exchange each weekday morning at 9 a.m. ET.
