Real conservatives stand on principle alone.
Newt has displayed very bad judgement in the past...he is a serial adulterer, someone what has been recently linked with extreme liberals and supported their causes.
And yes, global warming is a left wing extremeist view point. He supported a left wing whack rino in new York state and has been seen supporting causes of such people as Nancy pelosi, chuck schumer and other nut jobs on the left.
Newt is a no sale and if nominated the conservative wing of the republican party will take our issues to a third party and run against the left wing GOP and the left wing democrats. We have no place else to stand so we will stand with our principles and a candidate and party that will stand with us....not the GOP that makes us stand in the back of the bus.
Horsefeathers. Trying to take the politics out of politics? There's a lot more considerations than principle.
