The "reason" is that your fellow liberals all agree with each other. What a surprise.
And you have no basis of knowledge to either agree or disagree, so being a mere dolt, you revert to form and dutifully (ignorantly and stupidly) parrot the words of the "academic" liberals.
Guy, Republicans have had plenty of times to name things after Coolidge. They never did. Even Hoover got a dam named after him. Coolidge, not so much.
Here's the real standard you can use to prove some is a great president or an awful one. List their accomplishments.
FDR-
1) Got the US Through the Great Depression
2) Won WWII
3) Created Social Security
See. REAL Major accomplishments.
Okay. Now let's try Lincoln
1) Won the Civil War
2) Freed the slaves.
See. REAL Major accomplishments.
Now. Calvin Coolidge
1) Failed to prevent the Great Recession...
2) Um... errr...ummm.. Wait, let me check Wiki. No, nothing really important. Fumbled a reaction to the 1927 Mississippi floods... and that's about it.
