No, he has spent a good deal of money in order to cover every county in the first four states and I believe it's 19 more states where the counties are covered, plus one possession of the US and he will keep adding more counties across the country. He knew he needed money to do this and that's why he keeps bringing in millions from individual supporters to do this task.
I've seen the numbers and he has spent way more than Trump - that's because Trump is relying on free TV coverage and general gatherings of people, for the most part, to reach voters.
Cruz does gatherings in a county or groups of counties where the people actually live and vote. There is a difference in their methods and Cruz's method gets more actual votes because it's local to the voters. Maybe Trump will be the candidate but I've seen Cruz win against all odds when he won the senate seat using this exact method. He was in my county the day before the election for the senate seat - on a platform with Sarah Palin and a huge gathering of local people. He won the next day.
This is what he did in Texas as well. Big ground game, lots of travel.
Thanks for the info.
