As we reported on The Scorecard this afternoon, Democratic Rep. Gabrielle Giffords leads in two polls taken in recent months in her Tucson-based district. The polls, taken for both Giffords and her challenger, show different margins, but the freshman leads by a number outside the margin of error.

A poll for Giffords' challenger, State Senate President Tim Bee, was conducted by Arizona Opinion, a leading Republican polling firm in the Copper State, between 5/15-23 among 500 likely voters for a margin of error of +/- 4.4%. Giffords and Bee were tested.

A poll for Giffords' campaign obtained by The Scorecard tells a different story. The Greenberg Quinlan Rosner Research survey, conducted June 18-22 among 502 likely voters for the same 4.4% margin of error, also tested Giffords and Bee.

The Tucson-based district is likely to be a key battleground this year, as both parties have signaled their willingness to get involved. President Bush visited last week for a fundraiser benefiting Bee, which the campaign estimated pulled in a whopping $500,000, while the Democratic Congressional Campaign Committee reserved $705,000 worth of advertising time in the district.
