Since dropping out, the Cruz campaign has said that they would not seek to block Trump from the nomination, but instead, try to influence the platform at the convention:
“The Cruz team really just wants to make sure the platform reflects conservative values so that conservatives are excited about turning out this November and in the future,” said Ken Buck, the Senator who chaired Cruz’s campaign in Colorado and plans on attending the convention as a delegate.
It would not be unprecedented for a nominee to suspend their campaign only to then restart their campaign at a later time—in the 1988 campaign cycle, Democrat Gary Hart dropped out in May of 1987 after scandals alleging adultery only to restart his campaign in December of that year.
Wounded by the scandals, his campaign performed poorly in the primaries and Hart dropped out shortly thereafter.
