This week on the Bottom Line I asked you to submit question via Twitter and Facebook. Some really great ones came in, and here are the two I answered:

From Rey Palma: "The tone of debates will be affected by a desperate challenger. There is little he can do to move the needle or is there?"

From Gloria: "How is Robin doing?"

Two good questions. Watch for my answers here:

Shoot me more questions for next week. And make sure you tune into " GMA" weekdays and "This Week" on Sunday.
