Consider Mitt's father role in getting Barry Goldwater's campaigned destroyed. Consider that Mittens was behind Evan Mullen's 2016 campaign that was publicly stated as being for the sole purposed of stealing votes from Trump. Consider how often Mitt goes against Trump for no logical reason.
Obama getting re-elected for a second term was very important for reaffirming his place in history. Who better then to select as an opponent than someone that is uniquely qualified when it comes to throwing a fight?
I didn't like Mitt, didn't vote in 2012. I can't remember how much of a fight he put up. Did he put up a fight? Or did he take all the abuse? Makes me wonder.
Romney was either bribed or blackmailed into throwing the 2012 election. In the first debate, Romney made Obama look like a drooling moron. But in the second debate Romney just stood there and took Obama's attacks. Romney also stopped campaigning completely during October.
Somebody got to him.
I have had my suspicion that Obama was spying on him and got something to blackmail him. Remember the CTH piece which exposed that:

He did something real bad and they blackmailed him!
Blackmail makes sense. Whatever they have on him is apparently still being used to manipulate his current behavior.
