Cruz's political strategy is really very simple and transparent....... he intends to exploit the smouldering anger re "politics as usual" among the whole electorate.
It worked against Dewhurst in Texas and if it doesn't work nationally, it will be because too many other folks are not as smart as Texans.
He's been doing that for 30 years. At least there isn't a lot of flip-flop baggage to contend with. It will be interesting to see when others announce, since Cruz is taking the full brunt of the Democrat owned media.
The only thing worse than a liberal is a liberal that thinks they're a conservative.
