I have also noticed that Marco is bringing up the KKK thing in all his interviews, while Cruz is not. Cruz knows this is a non-issue, and Rubio does too but he doesn’t care — this is the same crap Rubio was doing to Cruz for the past couple months — distorting records, taking things out of context, etc.
I actually think what Rubio is doing is hurting the party, not just Trump. I am sick of people calling Republicans racist. I don't believe Trump is a racist, and I think this ad is despicable. In hindsight, Trump should have known who David Duke is and immediately condemned him. But this is just crap what Rubio is doing.
That is why I think policy should be debated, not baseless character assassination.
Cruz mentioned it in his victory speech.
