Let's say that Presidents DID NOT have term limits and could run as many times as they like- with that said- how do you think elections would have turned out- to keep it simple let's say from Reagans term. Here's my analogy
1. Reagan in 1988 would have won again- albeit narrowly- I think he would have beaten any Republican challenger and would ave also destroyed Mike Dukakais.
2. Reagan would have been told old to run in 1992 and even if he tried would have lost- to Clinton- so Clinton would have won against any GOP.
3. 1996- Clinton landslide against any GOP
4. 2000- Clinton destroys Bush
5. 2004 Clinton would have given one last hooray and destroyed BUSH, MCCain or any other contender
6. 2008 would have had the same results- either Clinton would have passed the torch to Hilary who under those circumstances may have got the nod and beat out Obama but than again people may have got sick of the "Clintons" and Obama gets the nod and again either Obama or Clinton beats any GOP candidate running
7. I would assume if my scenario had happened more than likely no Iraq war- no housing collapse so the Dem in the White house beats out in candidate running in 2012 for the GOP.
Overall if Presidents had no term limits I would see many years of the left owning the WH- just my opinion.
