Sign of Impending Coalition?

The NDP candidate in London just dropped out of the race and puts his support behind the Liberal candidate.  Coaltion at work?  You decide.

An NDP candidate in London has surprised everyone, including his own party, by withdrawing from the election race and throwing his support behind a Liberal rival.
Ryan Dolby, who was running in Elgin-Middlesex-London, made the sudden announcement through a news release emailed to the media, party officials and others Wednesday morning.
"I am worried if Stephen Harper gets a majority. I made a strategic decision," Dolby said.
He was running against Liberal Graham Warwick and Conservative Joe Preston, who held the seat before the election.
Asked if he had warned NDP officials either locally or nationally, Dolby said he thought it would be best to let everyone know at the same time.
