Kevin Doyle: Homelessness issue is a threat to Coalition
Twice a week, Enda Kenny's personal mobile phone pings with a text message telling him how many people slept rough on the streets of the capital the previous night.
Yesterday, the figure was 122, including 21 women. The sender of the unsolicited text doesn't expect or even want a reply, although he sometimes gets one.
On St Patrick's Day (while about to meet Barack Obama in Washington) Mr Kenny became conscious of a lull in the messages and sent one of his own asking for an update.
