Come to think of it, did it really matter last time or the time before that or the time before that?
The most "experienced" nominees of the last 10 years were McCain and Kerry. Neither was a very good candidate and neither would have made a very good president.
So, yeah, Ted Cruz doesn't have as much experience as he should, but that doesn't really seem to be as important as it once did.
Experiencewise, Cruz 2016 has Obama 2008 beat (though that's not saying much).
I kind of think we’ll never need to worry about it.
