I ignore all such claims that Trump has become a conservative just recently. And I don't consider a lot of groups who claim to be conservatives as part of the ideology like neocons or whatever the ideology Glenn Beck's nuttiness falls into. Also free trade traitors are not conservatives to me either.
You want Trump to embrace Bernie, and what he represents, to attract Bernie supporters. Trump, and conservatism, doesn't need to pander to these minds of mush. What they need is a lesson about which side butters their bread. Trump can make that argument by explaining the differences between capitalism (freedom) and collectivism (slavery). That would be the smart thing to do, and it is what will work. Playing silly gotcha games may make you feel good and believe that you're winning, but that's all superficial nonsense that doesn't change the electorate in any in any material way, or that builds for the future.
But you keep focused on the bark, rather than the tree and the forest.
