There is no action without thought. You can't move a muscle without deciding to first.
First thing any person has to do when faced with an evil like Obama is to choose to fight back. Make a choice. You don't even have to get out of your chair to do it. Action will follow, but you've got to decide first.
Once you've done that, write to your elected representatives and inform them that it's their constitutional duty to demand all of the facts regarding Obama's "natural born citizen" bona fides. Tell them that they must demand proof that he actually meets the constitutional qualification to be President.
That's a good start.
Who's them?
