I believe Cornyn is probably the best. As far as I can tell, he is conservative and does not waver from that position!
On other hand, I would Not want Lindsey Graham (R-SC) because according to one site, he believes in the following:
* Voted YES on establishing a Guest Worker program. (May 2006)
* Voted YES on allowing illegal aliens to participate in Social Security. (May 2006)
* Voted YES on extending Immigrant Residency rules. (May 2001)
* Voted YES on more immigrant visas for skilled workers. (Sep 1998)
What does his position on immigrant visas have to do with his judicial philosophy?
