this call to debate has been posted here umpteen gazillion times now; you anti-Trumpers need to get some fresh dirt because posting your old dirt over and over and over again is getting REALLY boring.
And BTW, Cruz is simply copying what Jeb Bush tried a month ago:
it’s what losers do. they try to shine in the reflected light of the winners when their own light dims. on the other hand, the shinning winner can only be diminished by sharing his light with a loser, which is of course why winners shun sharing their light with losers.

It seems like the perfect solution is for Cruz to debate Jeb one-on-one.
