Conally likely becomes the nominee in 76. Nixon was willing to throw his full weight behind him.
Would he? I doubt that Connally, a former Democrat, would be able to overcome Reagan's popularity with movement conservatives. Moreover, Connally was put on trial in 1975 over a bribery scandal. He was indicted, but acquitted. However in a post-Watergate atmosphere I doubt that even Republican voters would respond well to Connally, especially if Nixon so publicly supports him.
