Fresh findings from Siena College give Governor Andrew Cuomo a 62-37 percent job performance rating — “by far the best it’s ever been,” according to the pollster. Cuomo’s favorability ratings, at 73-20 percent, are his highest since April, and the governor is even polling better among Republicans than independents. Eliot Spitzer, by comparison, was barely holding on to a 44-41 percent favorability rating by his second January.
