Paul Mirengoff of Power Line posts Sen. Tom Cotton’s (R-AR) statement of why he will not oppose the approval of state-certified electoral college votes when they come before the Senate. He writes, in part:
The Founders entrusted our elections chiefly to the states—not Congress. They entrusted the election of our president to the people, acting through the Electoral College—not Congress. And they entrusted the adjudication of election disputes to the courts—not Congress. Under the Constitution and federal law, Congress’s power is limited to counting electoral votes submitted by the states.
I find his statement logical and based in law. You may find his explanation persuasive. N.B., Although we share a family name, Sen. Cotton is of no known relation.
