Hey, well, look on the bright side... at least we didn't bring Chuck Percy out of mothballs. Talk about a kook.
The issue with Keyes isn't whether he is a conservative but a matter of personality/character.
The statement he made about H.C., no matter how he attempts to spin it, hurts him. It brings his character into question.
In addition, I've seen both Keyes and Obama on camera. Keyes isn't a dullard but Obama has a more welcoming on camera persona.
IMO, these are the two negatives Keyes has to focus on if he truly wishes to be competitive in this race.
Characterizing those that notice his weakness on these two issues as failing to endorse conservatism isn't accurate. It may be true in individual case but not for everyone that hasn't embraced his entrance to the race.
I do believe Republicans should work on his behalf to the best of their ability. Obama is a Liberal. Keyes endorses substantive conservative policy. The choice is clear for conservatives/Republicans in this race.
