Pardon Me

The power to pardon has been in the Constitution from the beginning.  George Washington issued 16 pardons during his 2 terms in office.  Only William Henry Harrison and James Garfield issued fewer pardons.  In fact, they each issued none on account of dying early in their presidencies.  John Adams, the sole Federalist president, only issued 20.  The power of the pardon has grown since then.  Let's see how that breaks down by party.

Independent

Washington didn't like the party system though he most aligned with the Federalist Party.  However, he spoke against parties so he's generally classified as Independent.  He offered 16 pardons.  John Tyler, the 10th President, was originally a Democrat but switched to Whig.  When he took over for William Henry Harrison, the Whigs disowned him and the Democrats didn't want him.  Thus, he falls into the Independent Party.  He offered 209 pardons.  Tyler lifted the average per president quite a bit.

Federalist

There was only 1 Federalist, President John Adams.  Following Washington, he was stingy with the pardons, only granting 20 in his 4 years as president.

Democratic-Republican

The Party of Thomas Jefferson, it primarily competed with the Federalist until they disintegrated after the War of 1812.  Jefferson, Madison, Monroe, and John Quincy Adams were Democratic-Republicans.  The party was much more generous with pardons, offering 917.

Democratic

Having lost the 1824 election, Andrew Jackson split from the Democratic-Republicans to create a new party.  This is the Democratic Party that continues to this day.  It is the most generous with pardons, averaging 1,489 per president.  This number does not include Andrew Johnson's blanket pardon for many Confederates after the Civil War or Jimmy Carter's blanket pardon to over 200,000 draft dodgers after Vietnam.  Franklin Pierce was the stingiest with pardons (142), while Joe Biden has more than doubled 2nd place FDR (3,687) with 8,027 pardons so far.

Of particular note, Joe Biden has dramatically lifted the average.  Removing Joe Biden's 8,027 pardons, drops the Democratic average to 1,053 per Democratic president.  How high will it go by January 20th?

This reminds me of Al Gore's hockey stick graph.

Whig

There were only 3 Whig Presidents and two of them died early in their presidencies.  The Whigs only issued 208 pardons.

Republican

The Party of Lincoln has had more presidents than its nearest rival, the Democrats.  A Republican president averages 701 pardons.  Calvin Coolidge offered the most pardons (1,545) of any Republican while George HW Bush offered the fewest (77), if we excluded James Garfield, who issued none before his assassination.

From Eisenhower to Trump (1953 to 2021), there were 8,126 pardons.  President Biden is going for the Guinness Book of World Records.
