A lot of "who attacks who" is based on VP aspirations. For example, no way is a ticket going to have two politicians from the same state and so Pawlenty feels free to go after Bachmann. Make no mistake, half the people who enter the Presidential sweepstakes do so to get a shot at VP.
Look for candidates who would - - geographically and temperamentally - - make good ticket pairings to mostly leave each other alone. We will soon see if Perry thinks Mittens is the front runner and wants a shot at being his running mate. Of course, if Palin jumps in (I am positive she will) we will get to see some interesting dynamics there, too. Some candidates are "all in" - - President or bust, ie., not at all interested in a VP role. Such candidates would include Mittens and Palin only, as far as I can tell. Of all the candidates it will be most interesting - - and telling - - to see what Perry does.
'Palin / Perry' does have a nice ring to it.
So far, Sarah Palin isn’t running.
Doubt if she will run against Rick. We will see.
Mark it, Rick Perry will stay in Texas and do just about anything with the rest of his life before he would be VP on a ticket with Mitt Romney.
Furthermore, he will beat Romney.
You are wasting time with that line of thinking, but I can’t stop you. LOL
