Talk of impeachment just serves to distract us from more feasible options.
When Congress is as angry as we are--Dems included--that may change. But they are partisan pansies right now.
The ONLY reason they did not attempt to impeach President Bush was because THEY HAD NOTHING ON HIM! They would have had to back up their insane so-called charges with FACTS and evidence of those facts. They had NOTHING, so they would have exposed themselves to all the world for the frauds that they were/are. By not attempting to impeach him, they can continue their insane rants and lies. Many have at least some degree of suspicion that there may be some truth to their lies.
There is no need to impeach the usurper...simply demand his birth certificate and have him removed.
