Everyone needs to sow the seeds of impeachment. Obama’s selective enforcement of the law is in direct conflict with the constitution. He ha done much more... but in this alone he could be impeached.
It is a slightly encouraging sign that the zeitgeist of politics is increasingly allowing for public utterance of the I word. But don't take Dewhurst seriously; he doesn't actually care one way or the other about impeachment. He just wants to get David Dewhurst back into office.
