There's something about Democrats and the Vietnam War that leads to long noses. Michael Blumenthal lied about his Vietnam Service, doing a tremendous injustice to real Vietnam Veterans. Worse, Blumenthal's apologies are unclear and he continues to rely on duplicitous lawyerly semantic statements to justify his lies.
This says a lot about character. You can expect Blumenthal to similarly play fast and loose with the truth should he get into office in the Connecticut race. If Blumenthal wants to salvage his honor, the right thing to do would be to withdraw from the race. Maybe there's some reality series or game show he can do--like Elliot Spitzer.
