You were caught as a troll and now you are changing your argument.
You argued earlier that other Presidents have acted illegally. When I called you ln your dissembling and pointed out that Obama is different from any other President we have had, you have changed your story and now claim to have argued only that the congress is unable to impeach him as a practical matter.
Liberals lie. Conservatives argue principal. You are a troll.
It sounds like your delusions have overtaken the reality around you ... :-)
