A vote for Cruz is a vote for Rubio/Romney because the RNC is going to strip his delegates at the convention and give them to the GOPe designated loser.
On Wednesday morning, as we review the results of all the Super Tuesday races, if Cruz's only accomplishment was to skim a few delegates from Trump while winning no states himself -- then Cruz should drop out.
If all Cruz accomplishes is to split the anti-Establishment vote enough to guarantee a brokered convention, which the Establishment will use to anoint their designated loser, and hand the US over to Hillary, then Cruz should be treated as a traitor to conservatism.
