The report sparked speculation that former Florida governor Jeb Bush would also be targeted by Trump's Super PAC efforts, but the source quickly dispelled such rumors: apparently, Trump doesn't feel Bush has neither the credibility nor power to pose a serious threat to him. This is in contrast to the actions of Cruz and Kasich, with the two actively coordinating with each other to discredit Trump and the former outright rejecting him in front of thousands of Republicans gathered at the RNC in Cleveland:
“The person said that despite former nomination rival Jeb Bush skipping the national convention and refusing to back the Republican nominee, Trump ‘does not care' about doing the same against Bush because the former Florida governor is already ‘destroyed.'
During an event in Cleveland on Friday, Trump hinted at the prospect of funding an outside group against Cruz in the future.
‘Maybe I’ll set up a super-PAC if he decides to run,' Trump said of Cruz. Turning to his running mate Mike Pence he asked rhetorically, ‘Are you allowed to set up a super-PAC…if you are the president, to fight someone?'
The person close to Trump’s thinking indicated that Trump would consider forming the super-PAC whether or not he wins the presidential election in November. According to Federal Election Commission rules, if Trump doesn't win the presidency, he is clearly free to set up and fund a super-PAC. But if he occupies the Oval Office, the rules head into a legal gray area. Between elections, or if Trump declares himself a one-term president, he would be allowed to donate to a super-PAC, but is not allowed to solicit contributions of more than $5,000.
Kasich, 64, cannot run again for Ohio governor due to the state’s term limits. The 45-year-old Cruz is up for re-election in 2018. Both men have indicated an interest in running for president again in 2020, when they would either face Hillary Clinton or mount a primary challenge to a sitting Republican, Trump.
When contacted, the Trump campaign declined to comment.”
