Assuming there is a blazar type continuum in every radio-loud quasar, we findthat the free-free heating due to the beamed infrared continuum can greatlyenhance collisionally excited lines, and thus explain the stronger CIV$\lambda$1549 line emission observed in radio loud quasars. We further predictthat the CIV line should show variability {\it not} associated with observedcontinuum or Ly$\alpha$ variability.Comment: 15 pages, 3 figures; to appear in Astrophys. J. Let
