Its not the President that is going to make the necessary change. Its Congress, American business, and the America people.
1. Congress makes the decisions on domestic policy and passes legislation. The President can sign or veto the proposed legislation, but congress can override that veto by a 2/3 majority
"After passage by both houses, a bill is submitted to the President. The President may choose to sign the bill, thereby making it law. The President may also choose to veto the bill, returning it to Congress with his objections. In such a case, the bill only becomes law if each house of Congress votes to override the veto with a two-thirds majority. [http://en.wikipedia.org/wiki/United_States_Congress]
So what good is the President on domestic policy when his decisions can be overridden?
2. Look at the current credit/economic crisis in America. Greed and overspending on the part of business and the populus. Short of the SEC and Fed making mistakes, 90% of that is due to non-governmental factors.
3. The President [at this time] has the obligation to preside over foreign policy matters and matters of national security. Thus, the next President must have a keen sense of foreign policy and diplomacy as we do live in a now "global" community.
In as far as either major candidate (yes, there are four others), I don't think any of them have the intelligence and experience to meet today's requirements.
Congress, That's where we need a change. They are the branch of Federal Government that is responsible for 90% of our domestic policy. Make the change there.
BTW, The House is majority Dems and the Senate, tho is 49/49 Rep/Dem, the remaining two seats have aligned themselves with the Dems, giving them de facto control.
