This is an 800# the National Association of Home Builders set up to reach the senators to ask them to pass Obama's amendment. Got the email at work.
After dialing 866-924-NAHB (6242), you will be asked to enter your zip code and then be connected to your first U.S. Senate office. When the first call is complete, stay on the line and you will be connected to your second U.S. Senate office.
