You might try reading a thread that was posted about an hour ago in which Roy Beck of Numbers USA outlines all the things Newt Gingrich did as Speaker to sabotage efforts to enforce laws regarding illegal aliens.
Michele Bachmann does not have a record of working to derail illegal immigration enforcement. Gingrich does.
You Gingrich cheerleaders are worse than the Perry Fangirls.
If there are Perrywinkles I guess there can be Newtons.
Newt is a seriously loose cannon. Cain seems to be the polar opposite, if anything he ties his cannon down too tightly (would not sign the Susan B. Anthony pledge for months because he feared its language, taken literally, would commit him to something Constitutionally impossible).
