I've thought extensively how to handle this scenario (before and after) she gets the nomination. Here are a few thoughts on the matter:
1) Unlike Obama she has had formal executive experience (as Mayor and Governor). So, she's had to learn how to balance a budget. Given the explosion of debt under Obama this cannot be stressed enough.
2) They compare Obama's education with hers and say she is lacking.
- Obama hasn't released his records so we don't really know for sure his educational background. She has does have a B.S. in Communication from the University of Idaho.
- Stipulate that technically his might be better on paper, but note that Lincoln had no formal college, yet he is considered a giant. Likewise, Truman did not have a college degree,college education and is now considered a good POTUS. Conversely, Carter was in the top of his class at the U.S. Navel Academy and is widely considered one of the worst modern POTUS.
4) Indicate that Obama cannot be trusted. He has made little effort to keep his promises. i.e., unlike Obama you much more likely to get what you see with her. In other words, can we trust Obama to run this country for another four years?
5) Unlike Obama, she doesn't have a history of extremists in her background.
6) Unlike Obama, she is unlikely to ignore contract law and favor her constituency at the expense of the American people.
Do I know if Palin would make a good POTUS? Do I want her to be the one to get the nomination? Not sure on both counts. I am sure of this however. We cannot trust Obama to another term. He has been wasteful with what he has been given, unresponsive to the public opinion, more concerned with "fairness/social justice" than what is in the best interest of the nation, geared towards consolidating power in the Executive Branch at the expense of Democracy and generally seen as weak by opponents and unreliable by our allies. If it's her vs. Obama, we have little choice but to vote him out. What little we know about her indicates that she is not bought and paid for like Obama has been.
