Certainly, where we are with reference to the size and scope of our federal government is not where a lot of us would like to be, but the reallities of the world and the demands of the electorate are more responsible for the state of things than either party would probably wish for.
Generally, I believe the Republicans would prefer not to be as involved with social programs or world affairs as we seem to have to be and some Democrats and yes, some Republicans would probably prefer to not have to spend as much as we do on defense. I think the best we can hope for is some restraint in all areas, but no matter what it takes, we can not afford to skimp on defense.
