Regardless of who is elected:
From the day after the election until the end of 2013 we have a window to get the long term problems facing us resolved. If the weak ass politicians in DC push the problems in to the future with short term stop gap measures, we are screwed. If we get into 2014, midterm elections will cause the polarization to escalate once again.
The long term problems:
1) Deficit spending is out of control, trillion dollar deficits are unacceptable. Make the cuts, however painful. Take the pain now rather than creating a bigger problem for the future to deal with. Start with the waste in the DoD. Then take out the waste in Medicare.
2) Tax structure... whether you raise some or all of the brackets, make it permanent. No more of this temporary shit. Yes, politicians of the future can decide to change things again later, but don't force the issue by giving temporary brackets. It cause uncertainty and uncertainty is an enemy of progress.
3) Health care... we have wasted four years on Obama care... and it will not reduce health care spending per capita. We know the root causes of the continuing escalation of health care costs. Start addressing them. If you do not, we are once again screwed.
4) Education... in conjunction with the States, first get rid of the wasteful spending (especially the bulk of 15000 district offices/admin), then figure out what needs to be done to actually educate our country's youth. If not we are going to end up with more and more like Jarod/Ditzie/Webb/etc...
5) War on Drugs: this stupidity must stop. Prohibition does not work. Punish those that hurt others or break laws under the influence harshly, but otherwise legalize them and tax them like alcohol and tobacco.
6) Fix the tax code: it is a 70k page+ mess... eliminate loopholes/deductions/subsidies (all of them except the standard deduction would be great)
7) End the safe seats: end the rigging of House seats making the bulk 'safe' for one party or the other. It is allowing more and more extremists from the right and left to get elected. This is increasing the polarization in DC and creating havoc. Each state gets divided by the number of house seats into approximately equal populations. Those districts are drawn to be as close to a box or rectangle as possible.
The odds of any of this being done... slim to none... because the country seems intent on maintaining the two party polarization and silencing any third party that may arise.
