Because Hillary Clinton was one of the most powerful First Ladies in recent political memory, it shouldn't come as a surprise that Bill has been pushing the envelope of spousal advocacy for his wife's presidential run.
I think that President Clinton would probably be supporting Obama if he didn't have such an obviously vested interest in Senator Clinton's campaign and while it's obvious why he is exerting his massive influence in her favor, I can't help but think that his behavior is somewhat ignominious for who should be such a distinguished member of the Democratic Party. While it is fine - and expected - of him to endorse a candidate, I do not think that he should be out shilling for one as tirelessly as he is for his wife.
As much as I like Bill Clinton and wish that he could run again - damn you, 22nd Amendment! - I do not think that a Hillary presidency will be tantamount to a Bill presidency. Voters need to realize this fact and that - matrimonial pacts aside - Bill might very well support another democratic candidate.
That was a lengthy digression...
I was very surprised to find out that the families of candidates are sometimes reimbursed for their "services."
"Records show that Joe Lieberman’s presidential campaign paid his wife, Hadassah, at least $22,000; his son Matthew received about $34,000 and his daughter Rebecca about $36,000. The Bush-Cheney re-election campaign paid Vice President Dick Cheney’s daughter Mary about $81,000."
Is that even legal use of campaign monies? If so, what would/do political contributors think about their donations being used to line the pockets of the families of their chosen candidates?
