Welcome to the cbs overnight news, im michelle miller. We are three days away from a key race in the marathon run for the white house. The republican president ial candidates will compete this saturday in the first in the south primary in South Carolina. Frontrunner donald trump and jeb bush continue to trade jabs on the campaign trail, now bush has added a political heavyweight to his corner. Former president george w. Bush. Jeb bushs campaign is counting on the 43rd president to give his brother a much needed boost. Here is major garrett. President bush ended years of self imposed political exile and drew the biggest most enthusiastic crowd in South Carolina. By itself the upbeat rally cannot reverse jeb bushs fourth. The event did take the edge off a nasty day of primary politicking. I think the voters should vote for the candidate who has got the most opinionated mother. Former president george w. Bush came to South Carolina on a rescue mission for brother jeb. In my experience, the strongest person usually isnt the loudest one in the room. George bush made a mistake. Reporter recent attacks by g. O. P. Frontrunner, donald trump on the former president s 9 11 leadership had jeb playing defense. He didnt know that 9 11 was going to happen. He rolled up his sleeves.

Well bring a lawsuit if he doesnt straighten his act out. Ted cruz appeared unfazed. You cannot simply scream liar when somebody points out the actual position of donald trump. Reporter amid the ever nasery campaign, the brothers bush reunited to build momentum. I love my brother the i am happy that he came to do this. He can still bring it. Reporter after the rally, president bush told me he loved hitting the campaign trail. And likes jebs chances here in South Carolina. Doesnt secure the gop nomination. He also said that he might sue ted cruz over eligibility to run for the white house. One of the differences between jeb bush and donald trump is their positions on immigration. Trump called for the deportation of all illegal immigrants. Bush wants to give undocumented workers a path towards legal status. Jeb bushs approach is tempered in part by experience as governor of florida which has the the Third Largest hispanic population in the country.
