CBS had Ted Cruz at 22%, and now Quinnipiac has Cruz at 23%, just 2 points behind Trump. This poll confirms that the CBS poll was no one off fluke. Dat Steve King endorsement has worked wonders. It seems Cruz is grabbing all the good doctor's defecting supporters.
Trump has snookered everyone he can, and topped out. Now that the riffraff which has no business being in the debates are fading into oblivion and soon dropping out, those poling for them are not going to be going for Trump.
Some (Yeb's block) will most likely be going to Gang-of-Eight establishment GOP Amnesty Flipflopper fast-talker Marco Rubio... but most will be going to Cruz.
This was the plan the whole while and it's coming together NICELY.
