The Republican Party is the disloyal party, opposed to democracy as well as to the Democrats.

Haldeman's notes prove that Nixon sabotaged President Johnson's Vietnam peace negotiations so as to get himself elected. This was an act of treason.

John Dean gives more explanation of Haldeman's notes and why we can rely on them.

Reagan likewise sabotaged his country (working with Iran) to get himself elected. A few years later, he ransomed terrorists' hostages with arms for Iran, from which he also got money to spend illegally to launch an underground war against Nicaragua. That too was treason, I believe.

Since 2000, Republicans have instead cheated by rigging the elections. After gaining power by hook or by crook, they use it to swindle their country.
