I agree with the first part of your reply. But I surely don't think that an unwillingness on the part of elected officials to confront the porosity of our borders and all that subsequently results is limited to just one political party. All members of Congress, regardless of party, pander to the illegals and their legal and voting relatives.

The sizable population of Mexicans in states like Texas, Arizona, New Mexico and California causes members of Congress from those states to tread lightly on anything that would make that constituency unhappy. As far as what party panders the worst, last time I looked those four states had 4 of 8 Republican Senators and 42 of 96 Republican members of the House. That's as close to a 50-50 split as is worth talking about. And they all pander to the Mexican voters who got them elected.
