Does Cheney take over if Bush is impeached?
That would be bad. We have included Dick Cheney and the other core members of his team in the Articles of Impeachment, and Cheney is in our Model Resolution. Also Kucinich has introduced HRes 333 to impeach CHeney so he may be the first to go. Also any investigation of Bush would necessarily implicate Cheney. So it is very unlikely Cheney would become President by impeaching Bush. The Constitution (Article II, section 1) and the 25th Amendment specify who takes over the Presidency in case the higher up folks are unable to serve. Based on that law, Congress has established an “Order of Presidential Succession”. Basically after Cheney comes the Speaker of the House (Pelosi), then the President pro tempore of the Senate, then Secretary of State(!), and so on. More details here.
