A brilliant, knowledgeable, great debater, bombastic, erratic, arrogant, untruth teller - likely to implode? The questions should be asked and not ignored. The promises might not be implementable by him. Think about it.
Poor manager
Not work well with others
Depending on the unsubtantiated promise of him devastating Obama in 3 debates (and perhaps fear of how well Romney will do)
Health - Overweight and needs to be healthy for the grueling Presidency, could die early
Work ethic?
he mouths the latter, but look at what he does.
High negatives
Arrogance, brashness, off the cuff conclusions, oppositionalism
People waiting for him to implode
Effective Speaker, but drummed out by his members for his style and unpopularity
Brilliant, but erratic
Attacking, vitriolic
Ethics
6 Freddie Mac - Characterized self as "historian", then "consultant" but clearly influence peddler,
claiming not a lobbyist (though he has $200,000 membership fee for clients and hooks people
up) See
7 Lying, as above
Adherence to marriage vows (forgive him, but watch out for expediency)
7 Ethics violations - His claims don't ring true; 392-28 voted for ethics reprimand, all panels were
equal in parties, but he claims it was only partisan
Past behavior - As indicator of future performance
3 Cheating on wives
6 Making enemies, if point made strongly
How he works with other people
Pushed out as speaker
Poor manager, lots of ideas but little carry through and management
Undisciplined, erratic
Scorched earth policy
Criticism of others:
Gingrich on "social engineering by the right" - a weak issue
Takes full credit where not due, stretching
Created balanced budget - Already set up before he was speaker, only there two of four years,
Cost curve continued upward but economy raised revenues 20+ % (Duh!)
Reformed welfare - One of Clinton's pledges in first election, others involved included Santorum
and one other player who was critical
Gained first majority for Repubs in years - Actually, similar to 2010, it was a reaction to Clinton
and issues at the time, though he contributed to some degree
Defeated the evil empire - Actually criticized as pathetic what Reagan did
Reagan conservative - Criticized and insulted Reagan on floor of house and otherwise, but took
on label for expediency
