It's clear that O'Rourke is still doing TV and radio ads (at least here in Houston), so he doesn't care if it's a 20th century tactic. He needs name recognition and he's getting it without Cruz countering. This 20th century tactic is called defining your opponent before he can define himself, and Cruz isn't doing it.
Maybe Cruz thinks he can overcome O'Rourke's media lead once he starts his own campaign. Cruz's advantage so far is that O'Rourke hasn't been attacking him, O'Rourke's been busy introducing himself to Texans.
Once they engage directly, things will be different. I just hope Cruz knows what he's doing by letting O'Rourke have the field all to himself over the summer.

I don’t really do social media either, but that’s how Cruz won Iowa and Trump won the nomination and general election. As has been said here before, no El Paso candidate has won statewide office in the collective memory of Texans here on Free Republic.
