1. Propose and pass a constitutional amendment limiting all Presidential Executive Orders to one year -- 365 days.
2. Propose and pass a constitutional amendment to repeal the existing amendment calling for popular election of US Senators, so that state legislatures elect or appoint Senators for 6 years terms.

If they still have time for things like impeachment, fine. But let's not make revenge the first and foremost issue the voters see.
