@snood,
I wasn't very hot on the "Reagan Republicans" - the winning factor for the Reps were the "Reagan Dems". Reagan was almost as dishonest as tRump.
I highly agree with your "after" reference. Reagan was after Bill Clinton got the US federal budget into surplus from the fiscal year 1998 to 2001, the only surplus years after 1969. Then Obama got the US out of a downward spiraling economy, the Great Recession and Subprime mortgage crisis created during Bush Jr's term.
.......and yes, the Republicans attempted to take credit for these Democrats achievements. tRump tried in vane to take credit for Obama's economic achievements despite McConnell's attempts to ruin his Presidency.
......and yes, this is the very same McConnell who has sworn to ruin Biden's Presidency.
What was the key to Clinton and Obama's success. Moderately higher taxes on the rich. Amounts they don't even feel because they have so much already. And, bettering the lives of the lower income - brining them ownership of homes, college for their children and more disposable income with fuller larders.
Whoa, wow, what a concept!
