Not infiltrate. Party invited them in by mimicking their platform to maintain and gain power for the sake of power, by bowing to the Dems self-acknowledged superiority, by actively destroying freedoms: allowing the Dems to freely attack various fundamental segments of American culture and society, by ignoring pleas for help from those segments. Thus, the GOP became the lame, spineless, disorganized party it is today. Winning, in 2016, will be a stroke of luck, nothing more.
Rove & co just help push the propaganda in the right direction to get the horrible previous nominees.
No truer words were ever spoken.
