Sorry, but at this point that's all on Trump. For a principled conservative supporting Trump is like nailing jelly to a tree.
You're joking. Cruz was pro-amnesty up until November when he flip flopped on live television, lying that he had "never supported legalization" even though he had literally given several interviews where he made clear it was all still on the table.
Cruz is a globalist neo-con who manages to fool conservatives by sounding Christian and being strong on abortion. On virtually every other issue, from free trade, to the domestic terrorism at Trump rallies that he chooses to blame on Trump, Cruz is either insincere, a liar, or playing games to get votes.
"Principled conservatives" don't allow the murderess of Glen Doherty, Sean Smith, Tyrone Woods and J. Christopher Stevens to reach the White House... under ANY circumstances.
“For a principled conservative supporting Trump is like nailing jelly to a tree.”
You mean like something you better figure out how to do before the pack of hyenas set upon you and your family?
