Frankly in the US right now I have no idea who I would support. I obviously don't vote. If I were to be voting in the US I would normally favour the Republicans but there are many times I have favoured the democratic candidate.
Perhaps they will let you vote for your fellow Canadian, Ted Cruz.
Personally, I really don't see how the Republican platform as a whole is in line with the teachings of Jesus. The things Trump has said have been said by many other leaders in the Republican party, and it is certainly echoed in their policies. Of course, it could be that neither part fits will with Christian teachings.
What seems to stand out with Trump is his tone. He loudly says what others in the Republican party are whispering.
