You know I said this to Tallcal a lot of times... if they wanted to impeach Bush, they could have with any number of issues about the border from defunding and telling the border patrol not to do their jobs to allowing the Johnny Sutton to continue to be a US distric attorney.
You can pretty much do the same thing with Obama, he is continuing Bush's policies (imagine that) and fall under the same "not upholding the constitution and the sovereignty of the country" thing.
But you know the dems wouldn't or couldn't impeach Bush, no matter how much they hated him because they also want open borders.
By the way if you heard Dingel this past Friday, he said that immigration reform is the number two reason why our economy is in the dumps.
