Is that what happened?
No. Someone was looking at a porn site and inadvertently (or on purpose) clicked the "Like" button for Twitter. Since it was from a computer where Cruz's Twitter account was already signed in, it automatically posted the "like" on his Twitter feed.
oooh I didn’t know that was possible, I assumed it all happened within Twitter.... so someone may have clicked “like” at the porn site and it showed up on the Twitter feed???
Ok, well that makes it far far more likely that it did indeed come from someone operating the Ted Cruz Twitter account, but we still don’t know for sure whether it was Ted or a staffer. I have trouble imagining Ted doing his own Twitter, so I’m gonna guess “staffer” but it will be interesting to see how this plays out.
