Mr. Ridley, you apparently did not read the impeachment resolution, which directly references the failure of the executive branch to protect our right to fair elections. Specifically, Representative Hall charges that Bush/Cheney have conspired to remove our right to democratic elections by relentlessly pursuing a policy to outsource our vote casting and vote counting to private corporations using secret vote counting technologies. Additionally, she charges the Bush Administration has perverted the Dept. of Justice by using it to advance a policy of voter suppression and election fraud.

I hope this answers your question about the correlation between election fraud and impeachment.
