The Republican Study Committee last week secured enough support — 147 members to be exact — to sustain a presidential veto of Democrat-passed appropriations bills that exceed the White House’s spending requests. Much has been made of the accomplishment, but so far there’s been little focus on the 54 Republicans who chose not to add their name to the letter.

That fact that Republican leaders, conservative stalwarts and even Appropriations ranking member Jerry Lewis (R.-Calif.) signed the letter is an indication that the effort has widespread support. So why did 54 Republicans not make a vow to hold the line on federal spending? I don’t have the answer, but these men and women might.
