Laundress,
I agree with you about his family. They don't deserve the mud-raking and nastiness which they will be going through.
Especially not his poor wife.
That said, when I said "tailing", perhaps I used the wrong word. After the Federal Prosecutor scandals and the Governor Siegelman affair, it seems to me very realistic to assume that the Republicans would be out looking for any and every possible weakness.
Not saying there aren't Democrats with similar disgusting habits, just, not since Tricky Dicky and Co. has anything even come close to what has gone on since 2000.
To me, the only relevant question is, did he mis-use public funds for personal advantage? If, as appears (I haven't read the NY tabloids yet, I need that first morning pot of coffee to even tackle the NY-Times, much less turn on the screen wipers for the Post) to be the case, he really was 'only' paying for the lady's time, then the matter is between him and his wife.
Granted, the hypocrisy is pretty bad. But, gosh, he's a politician...you aren't dealing with a used car salesman here, so you mustn't expect too much.
By the by, here in Germany, our own politicians love to sell themselves as purer than the new-driven snow. Just in my province, Bavaria, over the last few years we have had the anti-gay, anti-protestant, anti-abortion, anti-single mother benefit, anti-immigrant, anti-you-name-it Minister of the Interior resign because she got caught diddling her State provided driver. Another ultra-super-Catholic Saint in the making divorced his mentally ill wife and left her for a much (much much much) younger woman after knocking her up. Then tried to have his now ex-wife denied her share of their considerable fortune.)
It's the same all over the world. We don't get so upset about these things here because we have other double morals, but let's face it. The louder someone protests how much he hates gays and prostitutes, the more likely he is to be speaking from copious experience in the matter.
