Your point, that a promise on the lot doesn't carry forward to the contract, if you sign the contract without it containing the deal you bargained for, is not in any way similar to the gubermint lying to get your signature. The legality would be in question all the way through the court, up to the point that the judge ruled. Legality is a coin toss any more. I guess by your stance, you're all for Army Recruiter's lying to get people to join up. Strange! Blackbird.
There is also no doubt that the troll on the by line is a clinton apologist. And H T wouldn't know the truth if it hit her in the face.
