Trump said the same on the Bush taxcut extension. He said let the Dems cause it to elaspse and cause an economic slowdown. When the GOP take the House in 2009 they will have a stronger position to force the Dems to reinstate the taxcuts premanently. Again it is common sense tactics yet the GOP did the dumb thing, extend the Bush cuts for only two years and give the Dems breathing room to regroup and strike.
So the GOP is in a position of strength to fight for the Bush tax cuts but they aren't in a position of strenght to fight for cuts in the budget.
Look at your two paragraphs. You describe a Trump strategy in paragraph one that contradicts the strategy in paragraph two.
Unbelievable.
What Trump was saying that made sense was when the GOP won the House in 2010, the GOP should not have made a deal with the sitting Dems in the House just to extend the Bush taxcuts because all they got was another 2 year extension and kept the US economy from relapsing. It prevented the Dems from being blamed and allowed them time to regroup and come back in 2012 to argue tax on the rich only. Instead led the economy get worst and the Dems get full political heat just as the new GOP controlled Congress take their seat in 2011. Now the GOP is in a stronger position to push for permanent Bush taxcuts and more. What Trump understand is how to pressure the opposition for a better deal.
