1) Last night saw the first of two live TV debates between Keiko and PPK (the next is next Sunday) before the big vote day on June 5th (two Sundays from now). Without putting too fine a point on it, Keiko wiped the floor with PPK.
2) The latest voter intention poll came out last night, from IPSOS. Keiko is polling at 46.1%, PPK at 41.6%. This indicates a approx 53%/47% valid votes result forecast. The poll was taken to last Friday, i.e. before the debate last night.
