Cruzs intention is to destroy the party so that Democrats control both houses and the White House forever with a tiny but ideologically pure Republican party in opposition.
Actually you have it exactly opposite. You are describing the McConnell do nothing tip toe to the next election plan. McConnell and nearly all of the Senate GOP are quite content with their status as the minority party.
I really don’t understand why McConnell goes along with this since he faces reelection in 2014, but at least he is honest in his feelings, unlike the RINO from TN Lamar Alexander who also faces reelection next year
