Never. Sorry, but, never. That is the double-standard under which we live. After the horrid attacks on Sarah Palin and her family, including minor children, there are no rules anymore about attacking family members, even children. At least, on the Republican side. Everyone is fair game.
I do find this politically stupid, however, since Ann Romney seems to be Mitt's best asset (which is why she is being attacked) because she is well liked by the general public. Rather like Laura Bush was very well liked by the American public. I just don't see attacking her as being beneficial to the Obama campaign.
I find her as phoney as Romney and just as plastic...as do many others. Only those IN Romneys court would say she's “liked”.....most haven't a clue about her....or of Romney for that matter...they both wear masks glued tightly to their otherwise face we should know but never will.
