A Republican presidential debate on March 19 in Portland, to be produced by Oregon Public Broadcasting and carried live on pubcasting stations, is still on, despite GOP hopefuls Mitt Romney and Ron Paul pulling out of a debate March 1 in Atlanta, the Oregonian is reporting. Another debate on March 5 on MSNBC also has been cancelled. Greg Leo, chief of staff of the Oregon Republican Party, cosponsoring the March 19 event with OPB, PBS, NPR and the Washington Times, said the Portland debate is attractive to the candidates for several reasons, including that it will be carried by public broadcasting and thus reach households that don’t have cable.
