What is the dominant method of execution in the US today?

The dominant method of execution in the United States today is lethal injection. This method is preferred due to its perceived humaneness and the ability to administer it relatively quickly. However, some states also allow alternative methods, such as electrocution or gas chamber, depending on their laws and the availability of lethal injection drugs. As of now, most executions are carried out using a three-drug protocol involving an anesthetic, a paralytic agent, and a drug that induces cardiac arrest.
