E. Howard Hunt and G. Gordon Liddy got caught. Hunt was an old school pro and close friends with Allen Dulles. He was also directly employed by future Bush FBI director Robert Muller, before joining Nixon’s team. After committing a string of crimes for Nixon, he served a mere 33 months in a low security federal prison.
Liddy served a slightly longer 55, then got a series of sweetheart media deals from his friends in conservative media. He was the top speaker on the college circuit in 1982, three years after leaving prison.
Several Republican senators visited Nixon before he resigned because it was too politically costly for them to not vote for impeachment.
Lead by Goldwater, a major Nixon rival for leadership in the party. Ford was Goldwater’s pick for the VP slot after Agnew resigned as well.
In contrast, there weren’t political consequences for voting against Clinton’s and Trump’s impeachments.
There was a big reward for Lieberman when he voted for impeachment. Gore put him on the VP ticket.
Meanwhile, a handful of Republicans who voted to impeach Trump - most notably Liz Cheney - got primaried out of office.
