CHART: Here Are The Most Productive Members Of Congress

If it is by who sponsors the most legislation in the 113th Congress thus far, then it would be Sen. David Vitter (R-La.) and Rep. Alan Grayson (D-Fla.) for their respective houses.

If it is by whose legislation most often makes it through committee, that gets a bit tougher to figure out. Sen. Ted Cruz (R-Texas) has the highest 'batting average' with seven of the eight bills he sponsored having made it through committee. But Ron Wyden (D-Ore.) has had 13 pieces make it through committee, although he's sponsored 47 different pieces of legislation.

On the House side, it's even more confusing. Multiple congressmen have sponsored just a single bill, which made it through committee. Thus, they have 'batting averages' of 1.000.
