I like Erin O'Toole's proposed Generation Kickstart program to help young graduates by offering them a generous Basic Person Exemption for their first 3 years out of school and an "Extra" Kickstart to those in fields where their skills are in short supply - doubling that Exemption to be used over 5 years. Also a great and timely proposal to pursue a trade and security pact, CANZUK, with 3 of our Commonwealth partners: Australia, New Zealand, and the UK. 

Chris Alexander's considerable diplomatic experience (particularly given his time in Russia and Afghanistan) as well as his stint as Minister for Citizenship and Immigration would serve him - and Canada - very well on the world stage as well as on the domestic front.

Michael Chong's approach to Carbon Tax sounds credible. Always loved his views on democratic reform.

Pierre Lemieux, and Lisa Raitt have also impressed me for various reasons.

Suffice to say there is a good slate of candidates from which to choose.
