McCain/Obama tax plans....

Also being a fiscal conservative, and being familiar with the effect on revenue to the government (a major increase) that tax reductions have had every time they have been enacted, including those of Kennedy, Reagan, and Bush, I would say that in time of war while the deficit is so huge would be one of the best times to reduce taxes. Of course, as a fiscal conservative, I think that anytime is a great time to reduce taxes. We just have to make sure that Congress doesn't look at all that new revenue and think it is theirs to spend.

Fiscal conservatives don't typically believe that during times of peak spending (aka war) that government revenues should be cut. Deficit spending bad.

Econ 101: You can't have guns and butter.

None of those Presidents were cutting taxes during wartime. Reagan and Bush also had MASSIVE increases in government spending (that greatly outstripped revenue, increased or not.)

The oft-repeated Republican theory about the Laffer curve is provably false, but falls outside the scope of this thread.
