I think it's more the American people looking for a change every 8 years, than presidential term limits.
That's just it though. Congress is where you make real change. The president sets a tone, he does not actually write the laws.
Well I agree with you on that. I think we are in desperate need of term limits for congress.
I'm not sure about abolishing term limits for the president, however even if we did I don't think, in today's climate, anyone could win more than 3 terms. I've always thought extending the presidential term would be better, because most presidents are too focused in their 1st term, on running for their 2nd. Plus, the best thing for our economy is stability and predictability, having a possible direction change every 4 years causes a lot of uncertainty.
