McCain has 15-point lead over J.D. Hayworth in Kos poll

Arizona Sen. John McCain has a 15 percentage point lead over former Rep. J.D. Hayworth in this year's Republican Senate primary, according to a Daily Kos/Research 2000 poll released Friday. McCain currently takes 52 percent of the GOP primary vote, compared with 37 percent for Hayworth. That's not an overwhelming lead for the four-term incumbent, but it's an improvement over the 7 percentage point advantage he held in a Rasmussen poll taken last month. In addition to his polling edge, McCain has a strong cash advantage over Hayworth: the senator reported raising $2.2 million in the first three months of this year and ending the quarter with $4.5 million in the bank, while Hayworth reported raising more than $1 million dollars but has not provided exact figures.
