It's because that's ALL they got to do ... they have no platform the majority of voters support. Lie, deceive, redirect, create fear ... that's their strategy to victory ... LIE in public .... get called on their lies, they retract their lies in private when there isn't a large crowd to cheer them on. And with Donald Trump, it will be magnified 10X ... its going to get interesting between now and November for sure.
Congratulations on describing the playbook of most liberal and RHINO's. And you are right. With DT in charge (Oh hell, just with him in the race) it WILL get at least 10x as bad.
That is one of the many reasons I am a Cruz supporter (besides, he's from Texas. lol.). He does NOT lie. DT had to go back (of course he only did it once he won the nomination) and take back all of the nasty lies about Cruz he said.
Personally, I don't think debates between a murderess and a deceiver will be very interesting. Cruz vs Hillary would only be interesting in as far as seeing how harshly Cruz would DESTROY at the voters booth.
