In my opinion it is precisely because the media can use her to say "Conservatives Call on McDaniel To Give Up Fight Against Fraudulent Election"
Hence the Politico stories and other media reports today citing Ann Coulter's attack on McDaniel.
Had she attacked Obama/Biden/Hillary/Other Liberals today there wouldn't be ANY press stories about her.
So Ann is going to go where she sees opportunity. She tried to hitch a ride on Chris Christie's train. That didn't work. She became the biggest Romney-advocate/groupie one could imagine.
And this election cycle how she has made headlines is by being the attack dog for the establishment (of both parties) against the Tea Party movement. She has criticized tea party groups for supporting conservative challengers that are running against entrenched moderate/failed Republican incumbents, yet has been noticeably silent about the establishment bankrolling millions of dollars to attack tea party candidates - including incumbents who are being challenged by liberal/pro-amnesty/pro-crony-capitalism challengers.
So for now, in my opinion, "we" conservatives are a useful punching bag for Ann to make a name for herself, and she will continue to find opportunities where she can say she is being the 'better Republican' by supporting the establishment's argument/candidate/issue over the conservative one. And the media will happily promote her views each and every time they run counter to conservatism.
Charles Johnson was the one who broke the scoops during the runoff - catching Cochran's campaign putting out robocalls and fliers calling the tea party movement and Chris McDaniel racist, saying that he would deny black people the right to vote, and that he and the tea party would block/oppose Obama's agenda so black voters must vote for Thad Cochran to help Barack Obama's agenda.
After Charles Johnson and others started revealing the election irregularities and allegations that Cochran's campaign paid black activists 'walking around money' to give to black voters to vote for Cochran, Cochran's campaign manager was forced to resign yesterday. Lots of things going on in this race still...
