I understand your thinking. However after 8 years of degradation of country by the community organizer, it is imperative we do not nominate someone who is more likely to lose to Hillary.
On pure agenda basis, I agree with you Cruz is more pure than Walker. What I am looking at is that Walker won 3 times in a bluish state. That shows me he can win nationally.
I believe an unrelenting, full-frontal messaging attack on Walker's hypocrisy and political misteps with conservative principles will allow Cruz to be elected. And Walker's recent betrayal to play nice with the Chamber of Amnesty in Arizon shows his anti-conservative, Blue Dog Republican colors again.
