Multiple reasons. 1) Many in the GOPe want the same basic things as ObeyMe wants, and are NOT, in fact, on "our side." 2) The MSM worships ObeyMe, and Democrats in general, and refuses to give any coverage or airtime to rebuttals. 3) The GOP (incredibly) still hasn't figured out how to use social media or any modern means of communication that bypass MSM filters.
yep...on all three accounts. Also 4) they play on defense and are scared of their own shadow. Guys with fairly bold ideas like Paul Ryan and Rand Paul have gone back into their shell to appease the left and their media rather than advance ideas.
