In the first book of Robert Caro's series on Lyndon Johnson, The Path to Power, he observes that in his time as a member of the House of Representatives, LBJ had introduced only 5 bills of national consequence (only one of which he actively pursued and none of which became law), that he made only 10 speeches in the House until 1948 when tactical considerations for his Senate bid required otherwise, that he barely participated in asking questions and making points of order, and that he was careful also to avoid supporting one side or the other even in private conversation. Caro concludes that:
During the eleven years that Lyndon Johnson served in the law-making body that is the House of Representatives, few of its 435 members had less to do with the making of its laws than he.
Restricting this to those who served for at least 6 years between 1937 and 1947 (excluding 1948 because Caro attributes LBJ's increased activity then as being necessary to support his Senate bid), which of LBJ's fellow Representatives were less active than him in terms of legislation proposed per year and House participation? Was this inactivity consistent throughout their careers?
