(CNN) – The father of Sarah Palin's grandchild is continuing to speculate on why the Alaska governor decided to abruptly resign her post, telling CNN Monday it's likely because she was overly stressed and wanted to cash in on lucrative offers.
"I think it's because she got a few offers and she decided to take the money and she was a little stressed out at the same time," Levi Johnston said.
Also appearing on NBC Monday, the 19-year old added, "There have been a few times when she talked about how it is a very stressful job. I can understand that, and then after the campaign we had tons of offers coming in and all kinds of ridiculous things."
He also said Palin wanted to do a reality show, though her children were against it.
"There was talk about it'd be nice to just take the money and run or do a reality show maybe or something easier," he said. "There was talk about it but us and the kids, we didn't want to do any of that."
Johnston, who himself has said he has received multiple offers for television shows, also said he thinks the Alaska governor markedly changed after her losing bid as the GOP vice presidential candidate.
"She wasn't as outgoing and I just didn't see the spark in her eyes about being the governor anymore," he said. "She became quiet, she would come home and just hang out in a room, you could tell something was wrong."
Declaring "fame got to her head," Johnston also said he would not vote for Palin after her latest actions.
"After what she has done now, quitting on Alaska, I don't really think she, being the governor, should have for Alaska. She means a lot to me, I would do just about anything for her, but I really don't think I would vote for her if she ran for president."
Palin spokeswoman Meg Stapleton has dismissed Johnston's take, referencing his own show business aspirations. "It is interesting to learn Levi is working on a piece of fiction while honing his acting skills," Stapleton told reporters last week.
Johnston is the former boyfriend of Palin's daughter Bristol and is the father of Bristol's baby.
Meanwhile, Palin told the Washington Times in an interview published Sunday she plans to spend her days out of office traveling the country on behalf of candidates she supports - even if they are Democrats.
"I will go around the country on behalf of candidates who believe in the right things, regardless of their party label or affiliation," she said.
Palin has already reportedly signed on to headline an event sponsored by the Republican Women Federated of Simi Valley, California in the Ronald Reagan Presidential Library next month. She's also being courted to keynote a major Iowa Republican event next fall.
