Picking Rep. Paul Ryan as his GOP running mate is working for presidential candidate Mitt Romney. According to a new JZ Analytics poll conducted after Ryan was picked on Saturday and provided to Secrets, the race is now dead even, 46 percent to 46 percent. Only 8 percent of likely voters are undecided.

“Hot on the heels of Mitt Romney’s vice presidential choice of Wisconsin Congressman Paul Ryan, the race between Obama and Romney seems to be tightening. There is little doubt that Romney’s choice of Ryan has excited the Republican base, 88 percent of whom now support the new ticket,” said the poll. JZ Analytics, founded by Jonathan Zogby, is the heir to the Zogby poll founded by his father, John Zogby.
