It may do that. However, it is almost impossible to take away entitlements from a society once they are established. It is difficult to recover rights once they are surrendered. It is very difficult to cut programs once they are in place.
If the liberals gain a lot of power and screw things up even worse than the RINOs have, it will likely produce a backlash and a conservative renewal. That however doesn't mean that the damage will be undone. It doesn't mean that we won't be paying the price for many decades to come.
Some of the programs might get cut, and the growth of big government might be slowed, but actually shrinking the reach of the government is a nearly impossible task in most situations, and depending on which conservatives you are talking about they might not even seek to shrink the the reach of the government. Much of the religious right seems to advocate increasing the reach of the government, just into different areas than the Democrats typically do.
Suggesting that you have to make our government more liberal before people will rebel against is is counter-productive. It is saying that we much be defeated before we have any hopes of victory. If your victory depends on backlash after a defeat, your victory will likely be fleeting at best.
If you want to win a lasting victory, you need to build a solid foundation and expand it.
Stop talking about how things might get better sometime in the future, and work to make them better now. If you are always saying things will be better in the future that future is likely to remain a long way off.
A rallying cry of "don't worry, things are going to get bad enough soon that people will have to revolt" just isn't something I can get behind.
In fact, as a whole, things have been better this year -- with divided government -- than with Republicans in charge and expanding government, spending money and pushing for amnesty for illegals.
Fear of liberals isn't a good reason to elect RINOs.
