As Ross Perot said, there is not a dime's worth of difference between the two major parties. The benefactors may be different, but the effect on the country at large is almost identical. I wish the libertarian point of view had a much better representative than Ron Paul.
As I see it, the Democrats will spend more money on programs that we will regret in the future. They will tax the ultra rich more which will reduce entrepreneurial investment, which is how jobs are created. Then they will try to create a jobs program. At the same time they will not reduce federal government spending, except maybe in the defense budget, as Clinton and Carter did.
The Republicans will not increase taxes but will always be tempted to maintain the high level of spending.
We need a president who is motivated to reform the status quo in D.C.: reform the Social Security system, cut spending (maybe eliminate entire agencies and programs, reduce foreign aid, reduce farm subsidies to the big corporations), maintain vigilence against terrorism, eliminate all pork projects, attempt to rebuild our infrastructure, get new refineries built, develop new energy sources, etc.
