What these opponents fail to grasp is that we want formal amendments precisely because the informal amendment process has been used by the left to effectively turn the Constitution on its head. Why believe that Constitutionalists will have an upper hand through the formal process? Two reasons. First, Republicans control 31 state legislatures, which is where the work of amending the Constitution takes place. Admittedly, Republican is not interchangeable with Constitutionalist but it is nonetheless reasonable to believe that Republicans at the state level will generally be supportive of limiting the power of the federal government. Second, there are a few general philosophies of government which a vast majority of Americans believe but which can only be truly manifested in general Constitutional rules rather than specific legislation. For example, the majority of the American people want government to curtail spending and would support a cap on federal spending. That is a philosophy that is relatively easily expressed in a Constitutional rule but nearly impossible to express in the day to day budget wrangling amid special interests in Washington.
Regardless of your uncertainty, or even hostility, toward the idea of amending the Constitution, the simple fact is that it has already been amended, and continues to be amended, in profound ways, almost exclusively in favor of government power. Those who wish to curtail that power in meaningful ways have little choice but to invoke Article V. The alternative of complaining about the possibility of bad formal amendments while bad (and equally effective) informal amendments continue to multiply is nonsensical to say the least.
