Apparently, when it comes to political floor crossing, the Liberal party slowly collects those people who, because of moral principle and conscience, finally realize they have no place in the Conservative Party of Canada.
The Conservative Party, on the other hand ... well, let's just say they attract a slightly different crowd.
I guess it really is true that water -- and shit -- eventually find their proper level.
Mr. Khan won two elections as a Liberal, in 2004 and 2006, but took a surprise appointment as Mr. Harper's special adviser on the Middle East in August of last year — and then crossed the floor to the Conservatives last January.
"The more we worked together, the more both of us began to realize that, politically, we have an awful lot in common," Mr. Harper said when Mr. Khan crossed the floor. "In time, it became clear to me that Mr. Khan would be quite at home in the Conservative Party."
Truer words were never spoken.
