Let's see:Presidential approval rating in January ahead of re-election bid via @CNN:— Ryan Struyk (@ryanstruyk) January 20, 2020
W Bush 59%
HW Bush 46%
W. Bush faced John "Did you get the name of that Swift Boat?" Kerry.
Carter faced Reagan in our winter of malaise and discontent with Iran over our embassy.
I can't honestly remember who was Reagan's cannon fodder.
"Dewey defeats Truman" who invented the whistle-stop campaign.
Nixon faced McGovern who was on his second running mate before September.
Clinton faced Dole, who got a doomed Presidential run instead of a gold watch.
Obama faced two-time loser Mitt ,I'm richer than God" Romney.
Poppy faced Clinton. He never saw what hit him.
Ford pardoned Nixon. He never had a snowball's chance in hell.
It really is a matter of being fortunate in your opponent.
