This is payback by Obama, pure and simple...
Rep. Parker Griffith of Alabama famously switched his party to Republican, and his district includes Huntsville, AL, the home of Marshall Space Flight Center.
Rep. Sheila Jackson Lee of Texas gained notoriety from the Obama camp by endorsing Hillary Clinton's presidential run in 2008. Her district includes the home of Johnson Space Center in Houston, TX.
Rep. Suzanne Kosmas of Florida voted AGAINST the House health care bill, and she represents the FL district that encompasses Kennedy Space Center. Take a look at her picture on her House page, she has a shuttle there, for crying out loud!
