I will be interested to see the polling, later on, from the Republican block of senior voters, who do all the Republican voting, come rain or come shine, especially in the primary.
Who are they willing to vote for? Do they want Jeb? Are they open to a new generation, like young Rubio? Cruz and/or Walker?
Where is the Rubio support coming from? I would be interested to see polling on that, also. Is it the younger voter, or the Florida voters, or moderate voter? He seems to be running Jeb Bush a real race, for sure.
Could be the youthful looks & smile?
My guess is it's the younger and moderate voters that tip Rubio over the top in his state.
