Why won't Ron Paul cosponsor impeachment?

Ron Paul claims to be a defender of the US Constitution. Like all other members of Congress, he has sworn to uphold and defend it against all enemies, foreign AND DOMESTIC.

Why has he not signed on to the various bills for impeachment that have come before the House since 2004? If he is so concerned about the Constitution, why is he not following its mandate to impeach members of the Executive Branch who override the Constitutionally mandated separation of powers?  Why will he not vote to impeach those who lie to Congress, issue signing statements that override laws passed by Congress, refuse to allow Congressional oversight, etc? 

Ron Paul is capitalizing on the disaffection of Republicans for Bush and Cheney, who are leaders elected by GOP voters to hold the highest offices in the land. Yet Paul remains a loyal Republican, in the sense that he will not join the call to impeach Bush and Cheney for their obvious high crimes and misdemeanors.

Without impeachment, these criminals will go unpunished. Without impeachment, the precedents set by Bush and Cheney, that a "unitary executive" can override the Constitution, will stand, and will be used by future presidents to impose their will on the country.

Until Ron Paul cosponsors H. Res. 799, the call to impeach Cheney for lying us into Iraq and trying to repeat the maneuver with Iran, I'll consider him a hypocrite. He's so proud of his independent voting record, but on the issue of impeachment, the SINGLE MOST IMPORTANT ISSUE FACING THIS NATION, Ron Paul is silent.

HYPOCRITE!
