Blame is a tricky thing to assign in an election, and most of the substantial reasons for the difficulties of this election, I went over in a previous post. But there's no doubt that one key reason for why Cruz lost this one, was the inability of his supporters to convert those who weren't inclined towards him, to him. And one of the key reasons I've seen for that, and tried to warn against from early last summer on, was the ineffective and counterproductive obsession that many of his supporters had, to either begin their every comment with, or give prominent place to, an insult to those that they should have been trying to persuade.
So come on all of you out there (many of you Rubio supporters too, you know who you are) who've so enthusiastically enjoyed your memeing and shouting of 'Drumpf!', 'Stupid!', 'Cultist!', take a look at Cruz's loss and withdrawal from the race, and take the bow for it that you so richly deserve.
I'll do my best not to be bitter about it.
