First I'll agree with you that candidates should be dumped if they lie about who they are and what they've accomplished. But then let's get down to the real business beyond all the crap about the press investigating etc. If it's important, than have official procedures and processes for vetting candidates; otherwise it's all meaningless drivel fit only for partisan food fights. We don't even do security clearances before the person is a candidate - for a job that should absolutely require a security clearance. Fix that issue - security clearance before the name goes on the ballot - and this stuff basically goes away. At least it does unless they've quit asking a lot of questions I remember having to answer on security clearance forms.
Very basically if you lie about who you are and what you've done, you don't get a security clearance. If aren't eligible for a security clearance, your name doesn't go on the ballot and you don't go to congress or the WH.
