I’ll preface this with the fact that I watch the debates and read a lot to keep me informed of the upcoming elections BUT realize my bias and ignorance will still come into play.
<Simplifying> I’ve been reading a lot that a fear of the GOP is that Trump will leave the party and take his votes with him. This will weaken the Republican base and a Democrat will probably win. So based on that it appears one strategy appears to be ‘win at all costs’ (Republican in the Whitehouse even if it’s trump).
But conversely (or so it seems to me) that the GOP base feels that Cruz is the better choice. I’m basically a Dem but I have voted the other way in the past. As such, there is no way in hell that I would ever vote for Cruz.
On the other hand, I might be persuaded to take a closer look at Rubio for example. I have many like thinking friends who feel the same way. Given this, why not get behind someone who has the best shot at pulling in the middle or undecided voters. I understand that your first choice might be Cruz or Trump but if the ‘win at any cost’ theory is in play why back someone you know will get beat by Hillary?
