Yes he is.
His record proves it. He is rock-solid on national security, (including defense procurement and troop funding) Border security, and liberty, tax reform, He espouses the Big Issues. Unlike every single RINO running with the MSM blessing...he could comfortably give "The Speech".
He was there from the beginning.
And that brings to mind an old favorite...the Time for Choosing speech. It bears re-reading..think how much it reflects negatively on the defensive apologia's about "prosperity" being our security ...made so brashly and zealously by the Clintonites...and now their successors...?
