We discuss properties of QCD with variable and large $N_c$, taking intoaccount electroweak interactions; i.e., we analyze the generalization of thestandard model based on the gauge group $G={\rm SU}(N_c) \times {\rm SU(2)}_L\times {\rm U(1)}_Y$. General classes of solutions to anomaly constraints aregiven, and it is shown that these allow a $T_3 = \pm 1/2$ quark or $T_3=-1/2$lepton rather than the neutrino as an electrically neutral fermion. The issueof grand unification is addressed, and it is shown that $G$ cannot be embeddedin the usual way in a simple SO($N$) or SU($N$) gauge group unless $N_c=3$. Theratio of strengths of QCD and electroweak interactions is discussed.Comment: 10 pages, latex, uses ws-p8-50x6-00.cls and sprocl.sty (included);  talk given at the Workshop on the Phenomenology of Large N_C QCD, ASU (Jan.  2002), to be published in the proceeding
