Donald Trump says he could have bought Jeb Bush if he wanted.

Trump woke up a pretty sleepy round 2 after Bush claimed Donald offered him money in return for supporting gambling in Florida.

Trump fired back Bush was lying, and if he wanted to buy Bush's vote he could have done it in a heartbeat.

And then Trump shot a zinger at Bush. In case you hadn't heard, Trump previously accused Jeb of a cardinal sin in Presidential politics ... being boring.
