Perhaps, if we controlled both the House and the Senate with large majorities but this President has ignored the Constitution when it suited him and no one has stopped him.
Let's start by defining "we". Who are the "we" you are talking about - the GOP, or the Tea Party? At this point, I cannot trust the GOP to be any better than the Dems, so having them in control of both houses of Congress, IMO, is not an improvement. We might just as well have the Dems in control as the GOP.
But, beyond that, there are powers that the Congress gave the POTUS (NOT the Constitution!) that presidents from BOTH parties have abused. The Executive Order comes to mind. Since being granted the power of the EO, presidents from both the left and the right have abused the authority and it should be repealed and abolished.
IMO, all 3 branches of government need to be reset to the limits granted by the Constitution in order to begin restoring our government to what the Founding Fathers initially envisioned and immortalized in the Constitution. I simply don't trust politicians, regardless of party affiliation, religion, creed or anything else, to resist power grabs and exceeding their authority. Human nature, being what it is, drives most of us to take a mile when offered an inch. Therein lies the justifiation for a massive overhaul of the federal government that includes STRICT term limits for ALL elected positions!! NOTHING short of that is acceptable!!
