According to this the Iowa AARP folks are getting steamed that only McCain and Huckabee have RSVP-ed for their GOP presidential candidate forum on October 25. Seniors make up a key group of caucus goers. Spokesmen for Romney and Thompson replied to my inquiry that no decision has yet been made. Still awaiting word from the Giuliani camp. For now it seems smart for Huckabee, whose future may depend on a strong Iowa finish, to get in front of seniors regardless of who else participates. The next debate after tomorrow’s is set for October 21 in Florida. As they did with the Morgan State debate, the GOP hopefuls have to decide how best to use their time, but on this one there is no looming fundraising deadline. Who shows could say a lot about how hotly Iowa will be contested. Can Romney afford not to show if Huckabee does? If Thompson doesn’t show will this be an opportunity for Giuliani to score some points and make up some lost ground in the polls? We’ll find out soon as the candidates set their schedules for the next few weeks.
