Not always true. Take President Reagan for example. He was a good conservative on social issues. Yet during his 8 years, spending by federal government TRIPLED. He did not use his veto power enough to stop the democrat congress. It was the beginning of national debt explosion.
Next case...Bush-43. Pretty good on social issues! But he began another entitlement (prescription drugs) when the country was already burdened with Medicare, Medicaid, and 100 different forms of welfare benefits. Then he went along with big bank bailout. And increased spending by Dept. of Education. We just can’t afford anymore such morons regardless of how conservative on social issues.
Now the national debt is so high, Federal Reserve can’t even increase interest rates in line with inflation. Because the annual deficit will rocket up with interest payments on national debt. Printing money has never worked in every country where tried. Observe conditions in Japan. That is where we are headed. It will be the demise of this country. A bankrupt country can not defend anything.
I will support any candidate in 2016 who has the spine to cut federal spending. Because I look at long term.
