Because that worked so well for New Gingrich. /s
Obama is up for reelection in LESS than two years. Congressional energy should be channeled DIRECTLY at undoing what Obama (and Pelosi) have done, and to removing Obama using the ballot box. Impeachment talk will alienate the moderates that are abandoning Obama in droves. Why do anything to drive them back to Obama?
First, I don't think you understood my post. Speaker Boehner could establish an impeachment committee in the House to subpena documents relevant to Obama's constitutional qualifications to serve as president without so much as committing in advance to even a vote on an impeachment. The purpose would be to secure the documents and information necessary to determine whether impeachment is warranted.
Second, I have no difficulty distinguishing this matter from the different circumstances faced by Gingrich. I don't want to assume that you think that, because Gingrich failed, the power to conduct impeachment inquiries should be forever abandoned.
Obama's origins raise important constitutional questions and we shouldn't shrink from them merely because we are afraid that some folks might criticize us for insisting on the truth.
