It’s interesting that this shit is how Lyndon Johnson rose to prominence in the Democratic party. As a newly-minted Congressman in the 1940 election cycle, he acted as a conduit for Texas oil money, funneling it to various Congress and Senate races around the country and allowing the Democratic party to retain control of the House and Senate. This earned him the appreciation of Speaker of the House Sam Rayburn and FDR himself.
It also possibly won WWII, given the isolationism of the GOP at the time.
