Now may be the best chance we will ever have to pass an amendment limiting presidential abuse of the pardon power. Amending the Constitution is hard—it requires a 2/3 vote in both the House and the Senate, followed by ratification in ¾ of the states. Alternatively, 2/3 of the state legislatures can call for a Constitutional Convention, with ¾ of the states needing to approve any amendments drawn up at the convention. (See Article V of the Constitution for more details.)
The second method via Constitutional Convention is riskier than the first because a Convention could pass many amendments—some of which could destroy basic fundamental rights guaranteed by our Constitution. That is why none of the Constitution’s 27 amendments have been passed via Constitutional Convention. There have been no amendments passed in 33 years
It may seem crazy to think that we could pass an amendment now in the hyper-partisan environment that we are in. It is impossible to get the Democrats and Republicans to agree on anything, much less get 2/3 support in both the House and the Senate. But there is ONE issue that may unite Democrats with MOST Republicans—Pedophilia is bad. And pardoning a pedophile in return for getting possibly false testimony may be a bridge too far, even for some Republicans. This provides us an opportunity to pass an amendment to prevent future corrupt pardons and potentially reverse previous corrupt pardons.
