A second poll in as many days shows former Gov. Tommy Thompson with a significant lead over Democratic Rep. Tammy Baldwin in the Wisconsin Senate race. A Quinnipiac University/CBS News/New York Times poll released Thursday shows Thompson leading Baldwin, 50 percent to 44 percent.
The former four-term governor holds a sizable advantage (54 percent to 39 percent) among independents. He also outperforms Mitt Romney, who is in a statistical tie with President Obama after adding Wisconsinite Paul Ryan to the ticket.
In a Marquette University Law School poll unveiled Wednesday, Thompson also led Baldwin, 50 percent to 41 percent, cracking the magic 50-percent threshold. Both new polls went into the field within days of Thompson's narrow win in the crowded GOP primary.
Baldwin has released two television ads attacking the former governor since he secured the GOP nomination. In a spot unveiled Wednesday, Baldwin hits Thompson for refusing requests to release his tax returns.
The poll, which was conducted August 15 through August 21, surveyed 1,190 likely Wisconsin voters. It carries a margin of error of plus-or-minus 2.8 percentage points.
