Let's say Pelosi and the House actually do impeach Bush...

[WilliamPitt]

The impeachment procedure is in two steps. The House of Representatives must first pass "articles of impeachment" by a simple majority. The articles of impeachment constitute the formal allegations. Upon their passage, the defendant has been "impeached." Next, the Senate tries the accused. In the case of the impeachment of a President, the Chief Justice of the United States presides over the proceedings.

In order to convict the accused, a two-thirds majority of the senators present is required. Conviction automatically removes the defendant from office. Following conviction, the Senate may vote to further punish the individual by barring them from holding future federal office (either elected or appointed). Despite a conviction by the Senate, the defendant remains liable to criminal prosecution. It is possible to impeach someone even after the accused has vacated their office in order to disqualify the person from future office or from certain emoluments of their prior office (such as a pension). If a two-thirds majority of the senators present does not vote "Guilty" on one or more of the charges, the defendant is acquitted and no punishment is imposed.

...but fail to get the needed 67 Senate votes for conviction and removal.

What would this actually accomplish?

What other issues are worthy of being ignored during this long process?

Discuss.
