On Tuesday Jan. 6, the Democratic candidates will participate in the only radio debate of the election season. National Public Radio’s Neal Conan will host a two-hour conversation with the candidates, and this close to primary season, what they say may determine who wins the presidential nomination. The debate will be broadcast from Des Moines, Iowa, but we’ll ask the candidates a few questions that come from e-mail to email@example.com. The debate is scheduled from 2 p.m. to 4 p.m. ET. It can be heard on WEOS-FM, Public Radio for the Finger Lakes. WEOS-FM broadcasts at 89.7 FM and 90.3 FM in Geneva, and 88.1 FM in Ithaca. The debate can also be heard on line at www.weos.org.
