The potential exists for four intrastate rivalries for the 2016 Republican Presidential nomination.
First, we have Texas with Governor Rick Perry and Senator Ted Cruz.
Then, we have Florida with Senator Marco Rubio and former Governor Jeb Bush.
Also, there is the rivalry in Wisconsin between Congressman Paul Ryan and Governor Scott Walker.
Finally, in Ohio, we have Governor John Kasich and Senator Rob Portman as potential candidates.
Perry and Kasich have sought the Presidency before, although Kasich did so very minimally in 2000.
The best bet would be Marco Rubio and John Kasich among these competitors, as one assesses these eight political leaders at this time.
With Governor Perry being indicted, I think his prospects will be slimmer.
