Why give money from someone else's donation back to Black? Black's money was already spent by the campaign before it was brought to Paul's attention.
or to refuse to appear on the radio program of someone who believes that the United States government orchestrated the destruction of the Twin Towers and attack on the Pentagon
Because Jones is a syndicated radio show host, he has an audience of libertarians and populists/independents just like Rush has conservatives. His personal beliefs have no bearing on Paul.
Not all of his topics deal with wacko 9/11 conspiracy theories. He talks about privacy, sovereignty, abuse of government powers, etc. If you were ever on FR back in the late 1990s, we were talking about this stuff too.
or to reveal who penned those defamatory, racist, anti-Semitic newsletters if-as he claims-he is not the sole author?
Reports are coming out that Lew Rockewell authored the letters, but I'm not sure. But this is a dead horse. The Houston Chronicle covered this extensively in the 1990s.
The Jewish Task Force talks about those things too, which doesn't mean that the people who host cable access programs for that group aren't lunatics.
As far as I know, Paul hasn't agreed to appear on any of those program.
Why should whether someone is "nationally syndicated" have a bearing on your decision to appear, or refuse to appear, on his radio program?
If David Duke were somehow able to sign a national syndication contract with Clear Channel, would that mean that Paul should appear on his radio program?
Fr. Coughlin hosted a radio program that was more popular than the kookfest Alex Jones operates today, does that mean that the bilious, bigoted opinions he expressed on that program deserved the explicit endorsement of presidential candidates?
