Those poor, misunderstood big corporations. No one seems to know or care what a burden taxes are on those cash-stuffed companies—like General Electric, which paid no federal income taxes in 2010 . And don’t forget ExxonMobil, which made $19 billion in profits in 2009 and yet paid no federal income taxes —and instead, got a $156 million rebate from the Internal Revenue Service.

To make sure lawmakers and the public—mostly lawmakers, the folks who write tax laws—know about the crushing tax burden these abused corporations face, the Business Roundtable yesterday launched a two-week ad and lobbying blitz to push corporate tax cuts.

The National Journal reports the six-figure blitz will be an “inside-the-Beltway campaign” that will include “shoe-leather lobbying, earned media, a series of online videos and print advertisements . During the April recess, the organization will press its case in district meetings with lawmakers.”

One person the lobbyists won’t have to spend fancy Italian shoe leather on or too much time with is Rep. Paul Ryan (R-Wis.). His Republican budget proposal , released yesterday, is full of tax cuts and other goodies for corporations.

Let’s not forget, as the HuffPost Hill column points out, “Of course, we also have one of the lowest effective corporate tax rates. But who's counting?”
