My first concern is who of the other 3 remaining candidates has the best plans to revive our economy? Newt. Romney's and Santorum’s plans maintain the status quo.
Who of the 3 remaining candidates has the best chance of beating Obama? Newt. Personally I don't think Santorum (or Paul) can beat Obama. Mitt has a better chance of beating Obama than Santorum does, but less of a chance than Newt.
If Newt does win the presidency, does he have a chance of getting at least some of his policies implemented? Yes.
Relative to the issue of Newt withdrawing and endorsing Santorum, I say no way. It would serve no useful purpose.
you think newt can beat obama?....we would get blown off the map..1964 all over again...we would lose women by 20 points
