I think the source of his problem is that he effectively became a presidential candidate before he even showed up for his first day on the job in his second term as Florida governor. This had two implications in the minds of many voters:

1. They recognized that his entire re-election campaign was a fraud, including everything he said on the campaign trail.

2. They questioned whether he really believed in anything he did as governor in his first term — or if it was all just political grandstanding.

I would agree that his non-commit to his term is hurting him. When you are a national politician, you have a brand. If your brand says, you will quit, people will not vote for you.

That’s a good point.
