Chuckle!
They are the same polls, from exactly the same media companies who pump out all these polls giving TRUMP big leads in the GOP primaries.
Only difference is, the crazy Trumpbots gleefully and repeatedly post the mainstream media polls which show Trump with massive leads in GOP primaries and swear those polls are the Gospel, but then turn round and trash polls from exactly the same lamestream media, showing Trump getting clobbered by Hilary Clinton.
I mean you can't make this stuff up. You Trumpbots are so predictable. You are like children.
Same polling companies, different polls. They can cook the numbers for the general election because no one can call them on it. Cruz vs. Hillary just isn't going to happen. Iowa and New Hampshire happen next month. They have to compete with other pollsters for accuracy on those contests, which will impact their income for the rest of the election year.
