A compromise on border triggers between Senator Jon Cornyn and fellow other Republicans and the Senate's Gang of Eight could lead to a substantial number of new votes from GOP Senators for the immigration bill. They include Senator Bob Corker of Tennessee, John Hoeven of Nebraska and Mark Kirk of Illinois. Getting at least 70 votes in the Senate is seen by some as a large enough number to put pressure on the House to support the bill or at least pass a bill that is closer in substance to the Senate bill than the piecemeal bills now under consideration in the House Judiciary Committee.
