I believe one of our founding fathers (initials RWR) said that. LOL. Something about an 11th commandment and speaking no evil. He was talking about Republicans, of course, so I've embellished a little and applied it to conservatives.
Since you asked for a list of why anyone would support obama over keyes... I obviously have not one reason, but if you are actually wondering what Alan has done that is so polarizing, or what he could do to improve his standing amongst conservatives or republicans, or how his candidacy might be in any way damaging, here it is.
Alan would do better if he was perceived as obeying that commandment you just mentioned. Lots of bitterness against him on this forum and nationwide, is foundationed on unrepentant and terse statements he has made about our President, and in general, my party's leadership. If and when this race is over, his attitude towards attacking and blaming its leadership will surely become more apparent than it is now.
